Before E. B. White set about crafting Charlotte’s Web in 1949, according to Melissa Sweet’s biography Some Writer, he was “bringing a pail of slops to the barn” that he loved in Maine and thinking about a time not long before when he observed a barn spider spinning her egg sac and depositing her eggs. Weeks later, when he had brought the egg sac in a candy box to New York City, he found hundreds of spiderlings emerging and realized a story emerging as well. Michael Sims, author of The Story of Charlotte’s Web, quotes from a letter White wrote to some schoolchildren: “I didn’t like spiders at first, but then I began watching one of them, and soon saw what a wonderful creature she was and what a skillful weaver. I named her Charlotte.” E. B. White went to Willis J. Gertsch, author of American Spiders and expert at the American Museum of Natural History’s Department of Insects and Spiders, to learn. He spent a year studying spiders in order to get the story just right.
Face to Face with a Longhorned Beetle
In northern Utah last week I made a friend who happened to be a white-spotted sawyer beetle named Monochamus scutellatus. My children and I have been fascinated by these insects for years. If you are the most apprehensive and skittish adventurer in your group, chances are that this relatively large forest insect will glide in, land on you, and courageously stay, as if it had something to say. Like E. B. White and the orb weaver Aranea cavatica, this longhorned beetle and I had a face-to-face chat. What you will notice immediately are his long horns. These antennae were twice as long as the rest of his body, and that’s how you would know he was a male. The antennae of the females, in contrast, are typically only half as long. Both male and female have a distinctive white dot at the base of the wings, an easy way to distinguish them from the invasive Asian longhorned or velvet longhorned varieties.

This white-spotted sawyer said he is often misunderstood because of his appearance. He can’t help looking a bit creepy. He also sometimes gets blamed for damaging forests and wanted to set the record straight. He said that as a grub, he fed on the sapwood of evergreen trees that are already dead or nearing it. In fact, sawyer beetles invade trees following forest fires and in the months following mountain pine beetle attacks. They do not, however, kill healthy thriving trees. Sawyer beetles are, though, responsible for the familiar teeth-grinding sounds one hears in a wooded area as the fleshy larvae scrape with their mandibles.

At the other end of Utah perched in Monticello’s rabbitbrush a few days ago, I met a colony of striking Crossidius coralinus. Instead of mostly black bodies, these longhorn beetles boast vibrant reds and many more stories to tell. Thanks to beetle entomologist Ted MacRae, I am able to understand those stories better. I must admit that I will probably still jump when a longhorned beetle initiates a conversation from my forearm, but I now appreciate its point of view. After all, Charles Darwin suggested that “a taste for collecting beetles is some indication of future success in life,” and I will take all the help I can get.

Our Mormon Crickets

Children’s author George Selden described the impact of a cricket’s chirping in the bustle of a subway station in his book “The Cricket in Times Square” like this: “Like ripples around a stone dropped into still water, the circles of silence spread out. …Eyes that looked worried grew soft and peaceful; tongues left off chattering; and ears full of the city’s rustling were rested by the cricket’s melody.” Combine this musical talent with Jiminy Cricket’s gentle reminder to always listen to my conscience, and it is no wonder that I would drift to sleep on summer evenings enamored with cricket songs. How, I thought, could such a beautifully-sounding insect be the villain in Utah’s legend we know as the Miracle of the Gulls, memorialized in Minerva Teichert paintings and Temple Square monuments?

Decades later, near Fremont Indian State Park, I met a Mormon cricket for the first time. I cringed as I watched thousands of these creatures hopping across the mountain path that afternoon, and I understood how merciful those California gulls must have seemed, swooping in to gobble up the insects, as the Mormon pioneers struggled to develop a defensive, crop-saving plan as newcomers to this land.

Utah settler Mrs. Lorenzo Dow Young captures a bit of the incident in her 1848 journal entry: “May 27: …today to our utter astonishment, the crickets came by millions, sweeping everything before them. They first attacked a patch of beans…, and in twenty minutes there was not a vestige to be seen. They next swept over peas…; took everything clean.” These hordes of insects were not new to the area, however, as we know that explorer Peter Skene Ogden noted “crickets by millions” in his 1825 journal account over 20 years earlier.

Did you know that Mormon crickets are not crickets, grasshoppers, or cicadas, but large shield-backed katydids that walk or hop rather than fly? Their smooth, shiny exoskeleton can be a variety of colors and patterns, like the reddish-brown female I chased and studied this summer in Fishlake National Forest. They have long antennae, and each female has what looks like a long curving stinger extending from her abdomen. This ovipositor allows her to deposit 100 eggs or more that look like gray or purple rice grains just below the soil surface. The males, on the other hand, lack this structure, but they “sing” as a way to attract females, and reward their mates with protein-packed spermatophore prizes.

These insects can be solitary mountain-dwellers but make headlines when they swarm in huge bands, marching in one direction as omnivores, in search of anything to eat: cultivated crops, succulent forbs, sagebrush and other shrubs, other insects, and even their own kind. Researchers tracking migrations determined they can travel more than 50 miles in a summer, perhaps a mile a day, and for many, including those early Utah settlers and others hoping to shield crops from Mormon cricket devastation, it is a sign of relief to see the last one for the season. They do make for a great story, though.

Hi there, I’m a monster

I have a new spider roommate that I’ve decided to let stay. This is a bit of a development for me, though, since I’ve never been too keen on spiders, primarily because they’re spiders. They’re those strange land-lobsters that fall from the shower curtains, or appear behind a shelf; those horrid hairy hands that hole up in the bathroom sink to greet you in the groggy morning. “Hi there! I’m a monster!” they yell with delight. “Gahh! You sure are!” I yell back without it.

When I was growing up, I dealt with spiders according to the ‘all are bad’ fallacy. I was a spider killer I’m ashamed to say. I’d grab a wad of toilet paper, or a shoe, and send their bodies to the sewer or dump. As I grew older and learned more about them, however, I switched camps. I learned that they are just wee wolves who wait. They are not malicious or evil, even if some still take a deep breath to see. I then graduated to spider rehabilitator, and it’s where I am still rooted. I have a specific mason jar and slip of cardboard that I’ll catch the spider in, and then send them to the Oregon grapes beside my house. I find rehabilitation easier to cope with than believing that they are still all bad. I never liked killing. Once released, I know that they are actually happier back in their native habitat where they have an abundance of food and opportunity for spider hunting and other activities which behoove them. Maybe they’ll even get to eat or be eaten by an old flame.

But back to my new roommate. Our story begins a few weeks ago: I was brushing my teeth for the evening when I spotted them near the floor in the corner where my bathroom sink meets the wall. They were suspended in a wee web just living their life. About a quarter the size of a raisin, this little one was no threat I figured: they weren’t large enough to be seen as a scare, and, upon brief inspection, weren’t venomous. I decided to pass on an immediate capture and do it the next day or something. In their corner they stayed.

The next evening as I was again brushing my teeth, I was reminded that I would catch them as I saw them again. But today, this itsy spider was not alone: they had caught a hornet in their web and was gleefully doing with it that which spiders do. It surprised me though, that this small hunter in their own right was able to catch and turn a hornet at least ten times its size into leftovers. “Huh,” I thought, “Perhaps I’ll let you stay.” I like hornets less than spiders, and the enemy of my enemy is my friend.

Since then, the bitsy spider in my bathroom has caught even more, and is really doing me a favor. They have snared another hornet, several flies, mosquitos, and other unidentified organisms which I only recognize as tiny Tutankhamuns. My spider roommate has helped me straddle my rehabilitation camp with a new one: teamwork.

Now, while I still do catch other spiders and critters which find their way into my house, I’m allowing the roommate to stay, at least for now. I know there will be a day when my fiancé finally notices them and asks for them to go, but that day is not yet. Until then, I’ll continue to marvel at how my roommate, this eight-legged ecology major, takes on challenges that to us would seem plain mad. If you saw a hornet the size of a Kodiak brown bear, would you even contemplate catching it let alone eating it? That takes some gumption to not back down. I can admire that. So for now, we’ll keep working together, at least until hornet season is over. Then it’ll likely be to the Oregon grapes with you to find that old flame.

The Great Salt Lake: Important for Birds

I first met the Great Salt Lake in 1964 with two Central Michigan University college buddies on our way to Los Angeles. We heard you could float in its magical waters. Sure enough- it worked and we bobbed in its gentle waves oblivious to the many other virtues of this extraordinary water body.

This saltwater marvel is the largest wetland area in the American West. Its 400,000 acres of wetlands provide habitat for over 230 bird species traveling from the tip of South America, north to Canada’s Northwest Territories and as far west as Siberia. These wetlands and surrounding mudflats are vital habitat for 8-10 million individual migratory birds with many species gathering at the Lake in larger populations than anywhere else on the planet.

In 1991 the Great Salt Lake was declared a site of “hemispheric importance,” the highest level of designation given to a site by the Western Hemisphere Shorebird Reserve Network. The Reserve conserves shorebird habitat through a network of key sites across the Americas. Salt Lake receives the largest percentage of the world’s population of migrating Eared Grebes, nearly one-third of Wilson’s Phalaropes, more than half of American Avocets, and 37 percent of Black-necked Stilts. The lake’s shoreline, playas and mudflats also support 21 percent of the North American breeding population of Snowy Plovers, a species identified as one of greatest conservation needs by Utah’s Wildlife Action Plan.

These shorebirds are among nature’s most ambitious, long-distance migrants. But their numbers are dropping quickly. Shorebirds are showing the most dramatic declines among all bird groups. Species that undertake hemispheric migrations rely on specific habitats and food sources to survive, but these resources are increasingly under threat from human disturbance including habitat loss and degradation, over-harvesting, increasing predation, and climate change. As humans have continued to alter the landscape, shorebird populations continue to drop, with accelerated declines in recent decades.

Of 52 shorebird species that regularly breed in North America, 90% are predicted to experience an increase in risk of extinction. This includes 28 species already considered at high risk, and 10 imperiled species that face even greater risk.

At the base of Salt Lake’s food chain are microbialites, underwater reef-like rock mounds created by millions of microbes. These structures and their microbial mats form the base of the entire Great Salt Lake ecosystem, serving as a primary food source for brine shrimp and brine flies, which are the main food source for these aquatic birds. Falling water levels exposing the microbialites to air could trigger a collapse in the lake’s food chain according to a July study by the Utah Geological Survey.

So we humans aren’t the only one’s suffering from our disappearing Lake. Thank goodness we have awakened to this extraordinary resource found on our doorstep with many organizations and agencies attempting to save what remains for our health, wealth, and for the millions of threatened feathered friends that grace our skies, and our lives. Last May, Utah Governor Cox declared 2021 the year honoring shorebirds. We can do our part by taking action on conserving water and energy.
