Speedy Salenopid

Waiting to ambush

Waiting to ambush

Now that I’m working, I don’t have as much time to poke around in the desert watching for cool plants and critters. These days, Onelookout often concerns wild things discovered inside the house.

There’s been a spider living in the family room for a couple of weeks now. We see him on the wall, usually poised about four inches from the framed picture of Husky stadium. The aerial photograph from the 70’s encompasses many of our early hangouts and is a fond relic of college days at University of Washington.

When I first spied the spider I thought to whack him with my flip flop. But as I crept up, he easily nipped behind the picture frame. The lightning fast Salenopid crab spider watches with six eyes, and yes, he notices every move you make.

I’ve written about this crevice dwelling spider before…when a spider we called Flattie lived briefly in the laundry room. Salenopid crab spiders are mostly found here in the Southwest, and are known to consume lots of insects, but never humans.

With that in mind, I decided to let this spider remain in his hangout behind Husky stadium. We continued to see him now and then near the picture. Then Marc reported he’d seen Salenopid again, this time high in the stairwell.

The stairwell is some distance from the family room! Well, Salenopid’s a speedy guy and maybe our square footage about matches the territorial needs of a crab spider.

Later, I was reading about urban agriculture on the desktop, when a paper rattled on my desk. I looked down in time to see the spider scuttling sideways across the sheet. I could actually hear the drumming of his eight little feet.

I guess I’m getting better at acknowledging that we share this land with other natural beings. Maybe it’s learning to live with the spiders at the greenhouse, all in the name of Integrated Pest Management. In any case, I did not scream.

When Salenopid visited my desk, I just went into the kitchen. When I came back later, the spider was gone. We haven’t seen him since. I imagine that his vision of me, through all those eyes was the more terrifying, but I’m quite sure he did not scream either.

Another Unexpected Visitor

Ground snake in the pool net

Ground snake in the pool net

In a good monsoon season monster storms roll in packing high winds, lightning and absolute torrents of rain. Monsoon season is also exciting because wild critters show up in the strangest places.

Last week Marc found this colorful little snake swimming in the pool. It was a bit out of place there, because this is a ground snake (Sonora semiannulata). Small and glossy, these snakes grow to be only 19 inches long. Ground snakes come in a wide variety of colorings and markings, and are found in a wide variety of habitats, including Phoenix metropolitan neighborhoods according to Thomas C. Brennan of Reptilesofaz.org.

Desert species of ground snakes are nocturnal during the hot months of the year, so again it’s hard to say why this snake was in the pool in the afternoon. He should have been napping in a cool burrow waiting for nighttime, hunting time. Ground snakes prey on insects, spiders, scorpions and lizards, all plentiful around here in the summer.

Even more out of place was the tiny, and I mean tiny, ground snake the cats found in the house last evening. Boo and Bandit are pretty useless as far as ferreting out spiders and scorpions inside, although they do get motivated by moths. But the boys were beside themselves over this writhing little snake, and I had to push them out of the way to get a better look. At first I thought they had cornered a centipede.

The snake was no more than four inches long and about as big around as a piece of cooked spaghetti, but it was clearly orange with black bands, just like the snake pictured in the pool net.

Audubon’s Field Guide to Reptiles and Amphibians states that male ground snakes fight for the right to mate a comely female. They mate in both spring and fall and females lay clutches of up to six eggs. It takes 7-10 weeks before the snakes hatch out, just 4-5 inches long. Our monsoon visitor must have been brand new. Who knows how it ended up inside the house; Marc scooped it up and put it out where it belonged.

When I came into the kitchen this morning both cats were sitting in front of the refrigerator staring into the black space underneath. “Now what?!”
We pulled the fridge away from the wall, but found nothing lurking to surprise u

Feeling antsy

ant image
I’ve been overcome this week by creatures smaller than this type font. This happens every summer as the monsoon season edges in. I’m always surprised and horrified as my beloved nature invades the house and requires drastic measures…. poison even.

Every year their strategy is a little different. This year it started on Monday morning with a scattering of miniscule ants on the kitchen floor. Hustling around on my way to work, I scooped them up with a rag soaked in vinegar. Later in the day I scattered diatomaceous earth around the doorways.

A few hours later I find ants massing on the kitchen floor (while the cats sit nearby, apparently transfixed). Worse, a line of larger and even faster ants march in formation up the wall, under the cabinet light fixture and into the spice cupboard. Opening the door, I find an enthusiastic frenzy of ants mobbing the sticky honey container.

Somehow, from all the way outside in the hot desert, these (dumb?) insects “discovered” my gooey honey container! I must say I experienced extreme frustration and a semi-minor meltdown at that point.

Sent hubby to the store for pet-friendly ant spray. (Poison)

We sprayed at all the entrances to the house and behind the fixtures beneath the cupboard. Then I freaked out about spraying poison inside and mopped it all up. Living ants scurried ahead of me carrying dead (or dying?) ants on their backs.

Esteemed biologist E.O. Wilson says he never outgrew the “bug stage” that boys (and many girls) go through. He claims his groundbreaking study of ants came about because ants are easy to find, social creatures. Wilson discovered that each species of ants has its own unique culture. He found that ant societies are held together by chemical communication. Lacking sight and smell, ants thrive following the information-laden pheromone trails they leave for each other.

Those trails in our house apparently allowed the tiny scouts that entered our kitchen to communicate to the larger gatherers the location of not only the honey container, but the next day, the kaluha bottle in the booze cupboard. After we had cleaned up those two sticky areas, the persistent ants found still another pot of gold – the sugar bowl, tucked away and forgotten on a high shelf. (eeek)

As annoying as the ant experience has been, I have to admire these fascinating little critters that willingly sacrifice themselves to find a food source to perpetuate their community.

E.O. Wilson is 86 now, and spends his time urging humans to recognize the importance of all life. “Biodiversity is the totality of all inherited variation in the life forms of Earth, of which we are one species. We study and save it to our great benefit. We ignore and degrade it to our great peril.”

Summer Solstice Snake Story

gophersnake

I find I organize my thoughts and perceptions into patterns that if not entirely comforting, are at least expected, so that I can negotiate my days in a somewhat orderly manner. Maybe everyone does this.

Leave it to Nature to toss out surprises to jolt us from our comfort zone and even make our adrenalin rush.

My husband provided this Onelookout summer solstice report from the local golf course. He, or his golf buddy, shanked a ball into the rough and the two of them searched a grove of desert mesquite trees for the missing ball. Marc says a movement overhead caught his eye.

Wound gracefully in a nearby mesquite, about seven feet up, a handsome gopher snake cast its head about in search of prey. The three foot long reptile wore a striking pattern in colors of cream and brown.

When the snake saw the golfers it slithered smoothly down the rough barked trunk. Without seeming to hurry much, the snake quickly disappeared into a burrow at the base of the tree.

Gopher snakes are good burrowers, climbers and swimmers, but mostly of course they are constrictors. This impressive snake species provides us the great service of rodent population control. The snake Marc saw may have been hunting for lizards in the tree or even baby birds.

Even here in the Southwest desert, coming across a snake is always surprising and somewhat alarming. A snake in a tree, on a golf course?

My husband sounded pretty thrilled to experience a jolt of wildlife to spice up his day.

Give Me the News of the Earth

We start our day with Good Morning America, NPR or a faithful study of the daily newspaper. We tell ourselves we are staying abreast of local happenings and gaining perspective on world events. You could also say this media addiction is a mass exercise in navel gazing, because all of our news concerns…guess who…us!

Break free of attempts by the media to influence your thoughts and by the marketers to take your money. Find real news outside in signs from the natural world.

Outside you may hear a chorus of birds. In my backyard a verdin peeps incessantly while doves harmonize and a thasher provides the melody. Underlying the bird calls is a steady drone of bees come to visit the flowering plants.

In a deep canyon nearby I shuffle through sand and past boulders on a path made by water. The arroyo is laced with a string of golden-blossomed palo verde trees. Instead of water, bees flow by in a steady stream. Instead of the gurgle of water I hear the rising and falling buzz of these bees. Why are bees so buzzy?

Scientific American provides an answer from Gard Otis, a professor of environmental biology at the University of Guelph in Ontario who studies bee behavior, ecology and evolution.
“Bees buzz for two reasons. First, the rapid wingbeats of many species create wind vibrations that people hear as buzzes. The larger the bee, the slower the wingbeat and the lower the pitch of the resulting buzz.
In addition some bees, most commonly bumblebees (genus Bombus), are capable of vibrating their wing muscles and thorax (the middle segment of their body) while visiting flowers. These vibrations shake the pollen off the flower’s anthers and onto the bee’s body. Some of that pollen then gets deposited on the next flower the bee visits, resulting in pollination. The bee grooms the remainder of the pollen onto special pollen-carrying structures (on the hind legs of most bees) and takes it back to the nest to feed to the larvae.
When bumblebees vibrate flowers to release pollen, the corresponding buzz is quite loud. Honeybees (genus Apis) are incapable of buzz-pollination and are usually quiet when foraging on flowers.”

Outside we gradually become aware of the carefully calibrated systems that govern the remarkable relationships between thousands and millions of plants, animals, insects, microbes and minerals, as well as the currents in the oceans and the atmosphere.

Imagine, this astounding world that represents the resources that allow our existence evolved over billions of years, without any help from us. Perhaps more of us should be studying the workings of nature instead of the latest shenanigans of politicians and celebrities. Give me the news of the earth any day.

Fantastic Frogs

Couch’s spadefoot can be 3 inches or more in size.

On March 19 I drove out to the Superstition Mountains, under a threatening sky split with trembling shafts of sunlight. It had rained the night before and again that morning, and as my hiking pal and I set out on the Second Water Trail the cool air was heavy with humidity and sweet with the scent of desert plants.

At the outset the trail descended gently to a boulder strewn wash. It was obvious that in rain events water thunders here, draining mountainous faces that loom craggy and forbidding. Familiar desert trees were joined by lush vines, and lichen and moss sprawled across rocky stretches. Timid lupine, larkspur and hyacinth shyly presented their spectrum of blue blossoms while brittle bushes and creosote flowered in bold yellow.

We hiked for several hours and the day was warming when I noticed movement at ground level. Expecting a lizard, I was astounded to see a small brown frog hop across the trail. He reached the shade of a large rock and slipped out of sight. It was a canyon treefrog, known for cryptic coloring that helps it hide in a variety of habitats.

The canyon treefrog is usually found in rocky canyons in riparian areas. This might be in the desert, in desert grasslands or oak-pine forests. The frog survives in elevations up to 9800 feet, avoiding cold temperatures by retreating to underground burrows.

I saw another frog a week later. I was outside with my Mesa Community College aquaponics class when one of the students spied a frog. It’s an evening class and we often walk over to the greenhouse, adjacent garden, and aquaponics systems to work. As we approached the dimly lit garden, a large frog hopped across the path.

Our professor scooped him up and held him so we could all admire his olive green coloring and dark green blotches. “This is a Couch’s spadefoot,” Dr. Brooks announced. “When I was a kid these frogs used to be everywhere.” The frog’s large eyes bugged out at us from the top of its head.

Apparently back in the day, spadefoots were a common sight in the evening times, especially in areas with sandy soils where drought hardy creosote and mesquite trees grew. Back then people knew the eerie nighttime scream they heard on monsoon nights was the mating call of this frog.

Mating season coincides with the torrential rainfalls of late summer. The spadefoots are called from their underground homes by the drumming of the rain on the earth and by the rumble of thunder. The males come up out of their burrows and immediately start calling the females. In The Natural History of the Sonoran Desert, the call of Couch’s spadefoot is described as the bleating cry that a sheep or goat might make. I would guess most of us aren’t familiar with that sound either.

Females lay thousands of eggs which can hatch in as little as 15 hours. The tiny tadpoles transform quickly into frogs, driven by the rapid shrinkage of the pools where they spawned. The brand new frogs hide under vegetation or anyplace slightly moist, and eat and eat. They feed on grasshoppers, ants, beetles and spiders. This may be the frogs’ only chance to eat until the monsoon season rolls around again. The horny growths or “spades” on their back legs help the frogs dig down into their protective burrows.

Frogs in the desert strike me as improbable, and in these days, nearly impossible. But nature has found a way to put amphibians into our arid landscape and allow them to flourish. As much as Nature favors delicate yet resilient amphibians, humans have mostly stayed immune to their charms and ignorant of their ways.

A Plant Can Volunteer Too

Out in the side yard, where the air handlers crouch near the pool pump, each gobbling electricity faster and louder than the others, a white globe mallow has volunteered.

The mallow first appeared a couple of years ago, as a straggly shoot boasting elegantly lobed leaves. It has grown into a pleasing mound of green in a stark area between a short block wall and a vigorous queen palm.

We think of plants as stationary, but they usually make at least two journeys…the quest of the seed, and the return to earth. Whether this single mallow seed traveled on the wind or in the gut of a bird, it came to shelter in this place. Is it ludicrous to think that the palm tree felt pleasure when the seed trickled down through the gravel to the soil waiting below?

For the seed has now realized its full promise, and the globe mallow sprawls luxuriously at the feet of the palm, drinking deeply of its irrigation and providing shade and cover to its roots. An ever gracious volunteer, at this time of year, the mallow presents long slender arms laden with delicate, cup-shaped blooms.

The pleasing blossoms cluster along the pliable branches like faces of joy. Some are fully opened and visited by bees. Others are still in bud form, pale green pods shaped like tiny pointed domes. The petals push from these buds to form perfect teardrops, imitated in art and jewelry, then elongate into rose-like profiles that gradually unfold.

The globe mallow is one of the desert’s most drought tolerant mallows. Its nectar attracts bees, while on rocky wild hillsides, bighorn sheep graze on the plant. Globe mallows may be white, orange or pink and make a nice addition to natural desert landscaping.

No Place for a Cottontail

cottontail

Wednesday, as you may know, is double coupon day at Sprouts Market, and as I pulled into the parking lot I found a throng of people. Shoppers trickled out the doors pushing loaded shopping carts, and others headed in toting handbags. Most of the nearby parking spaces were taken and a line of cars inched along, drivers looking for an empty slot. The red brake lights of a Suburban glowed as it sat, half way out of a front row space, waiting for people to pass.

In the midst of all this, I was astounded to see a cottontail rabbit crouched on the asphalt near the Suburban. He was absolutely still and people parted and passed by as if he was indeed invisible. Suddenly the press of autos and humanity seemed ominous and horrible.

I peeled off my sweatshirt with the thought I could drop it over the poor bunny and rescue it from what must be for it a hellish scene. But as I approached, the rabbit lollopped off to shelter under a parked car. I kept herding the little critter away from the busy store entrance, but parking lots, storefronts and heavily traveled streets surrounded us.

Sprouts is one of the anchor stores of the busiest intersection in our community. This is the corner of 48th Street and Ray Road. Seven lanes of traffic travel along one arterial and eight on the other. Once for a writing project I sat for half an hour at the bus stop on Ray Road just east of 48th.

Sitting on the bench inside the plexiglas shell I was overcome by the volume of traffic that surged past, pulsing in waves created by traffic signals. As a driver, I’d scarcely noticed the bus stop, but as a pedestrian I felt exposed, vulnerable and completely out of my element. The sheer mass of machinery and the anonymity of the passing drivers sealed up inside their vehicles, closed off behind their tinted windows….well, quite honestly, I didn’t really last the full thirty minutes.

I quickly lost the rabbit outside Sprouts on Wednesday, as the rows of parked cars offered plenty of places to hide. In an effort to replicate the writing exercise that demanded a radical change in perspective, I wondered if a very urban population of rabbits may have found a niche in parking lots.

Small squares of green grass are offered up in these fields of asphalt, a paltry attempt to soften the glare and provide comfort and a sense of aesthetics amid expanses of heat and grit. Rabbits most commonly feed in the early morning and at dusk, and these strip mall lots would be quieter at those times. During the day parked cars offer shade and cover. Most natural predators would be excluded from this environment.

This strikes me as a depressing theory, but plausible. After all, coyotes do roam city streets, peregrine falcons hunt from skyscraper ledges and black bears turn up in the oddest places. There’s no getting around the fact that a cottontail rabbit was hanging out at Sprouts, early afternoon on double coupon day.

Kiwanis Trail -Then and Now

The Kiwanis Trail was the original access route carved into South Mountain Park. Alarmed by the assault on the highly scenic area by miners, 100 Phoenix citizens petitioned to have the mountainous region declared a national monument. Stephen Mathers was brought in as advisor on this effort and he recommended the group ask the Honorable Carl Hayden to introduce the bill in Congress, which granted the land to the city of Phoenix for $18,000. There was no money left for developing park amenities.

In 1925 civic leaders formed two teams for a friendly competition. Who could build more mountain trail in a given number of hours? By the end of a single morning Kiwanis Trail was shoveled and carved through a gorgeous rocky canyon, from the foot of the new South Mountain Park to the top of Telegraph Pass. Prominent city chefs held their own contests as they prepared a celebratory luncheon for the volunteers.

The mile long ascent through the canyon alternates rock strewn inclines with peaceful meanders along flatter terrain. The trail traces to the shoulder of the canyon and the rain washed arroyo below appears sandy, shaded and mysterious. The northerly view of the modern city skyline would have astounded the park founders.

On this slightly overcast day in middle February the canyon shelters many plants that are revealing early spring blooms. Blue grey brittle bushes crowd the trail and wave cheery yellow blossoms. Shy scorpionweeds dot the ground with royal purple flowers. Michelle and I take turns calling out the spring blooms we see; fagonia, four o’clock, creosote.

A cactus wren lights on a boulder near the trail, a long slender reed drooping from its beak. I imagine the bird scouting the region for nesting sites and building materials, puffed with the importance of the duty. Cactus wrens are continuous builders, working tirelessly on their football shaped nests. Typically the baby wrens will appear in mid March, and breeding continues into September.

We pass a large stone dam about two thirds of the way to the top, installed to slow the rush of runoff down the canyon. We notice another dam close to the base of the trail on our way down. The Civilian Conservation Corps had a camp at South Mountain in the 1930’s and constructed trails, roads, picnic ramadas and these dams.

A pair of rock wrens plays tag among the boulders, where they live off insects sheltering in cracks and crannies. The intact ribs of a large saguaro recline on the hillside, as if the stately cactus became tired and lay down one day, never to stand again. Perhaps this happened during the time the Hohokam shamans pecked petroglyphs into the patina on the walls of these canyons, so long ago.

Join In! The Great Backyard Bird Count’s Upon Us.

Don’t forget that the 18th annual Great Backyard Bird Count starts tomorrow and runs through Monday. This event spans both Valentine’s Day and the President’s Day holiday, so presents great opportunities to get outside with a loved one or a little one and share a love of nature.

This is also your chance to contribute to a scientific body of knowledge! The count reveals the current health of bird populations and in recent years has highlighted the impacts of weather events like polar vortexes on bird ranges.

Imagine that helping the world is as easy as sitting outside in your back yard for half an hour and making notes about what you see! You’ll watch for birds of course, but in the process you’ll see more aspects of nature unfold.

Last year, I hit the jackpot. Sitting in our backyard, in late afternoon on the last day of the count, I saw no birds for nearly an hour. The inactivity made me feel impatient, I’ll admit. It was a big relief to see that first mourning dove.

Between those that came into the yard to feed on nectar plants and brittlebushes and those that flew overhead, the numbers of birds I sighted added up quickly. By the time I finally and reluctantly went back inside to resume routine activities, I’d tallied up six species! Not only could I record the numbers, it was fun to observe what the birds in my backyard were up to.

Back inside, take up the cloak of citizen scientist! It’s time to log onto birdcount.org and record your findings. Last year 144,000 checklists were logged online over the four day count. For an activity that’s fun, educational, free, and a contribution to science, the numbers should be far higher. Come on, join in. Give the GBBC a try this year!

Let me know what you saw~
