“Dad, what kind of bug is this?”

Normally, I try not to get distracted when going up as steep an incline as the Wellsville Mountains—stopping and starting again is as much work as slowly plodding on—but, I decided that a side quest to look at a bug might give me an excuse for a much-needed breather. Besides, I probably did the same when my dad took my siblings and me with him on hikes up the Wellsvilles when we were little. He sure loved those mountains, and the long hike gave him an excuse to dispense little morsels of life wisdom along the way.

When I approached the spot the kids were huddled, I was expecting to supply some wisdom myself on this bug.

A second later, I stood perplexed. I was looking at an insect I had never seen before. The bug was the size of my thumb and shifted awkwardly in what little dirt could be found just below the bare ridge of the Wellsvilles. Its dark abdomen was covered in scaled layers that became light on the edges, making it look something like the stripes of a bee. Unlike a bee, it had no stinger or wings. Its head was the size of a small cherry, with the color similar—an off-red or even orange. The six yellow, almost translucent, legs were hefty enough to support the massive body.

The kids repeated their question. My first instinct, thanks to the tones of red and orange and never seeing anything like it before, made me want to quip that it was clearly from Mars. I checked myself when thinking how this comment would compare to the boundless wisdom of my dad. In a moment of rare restraint, I told them that I had no idea and would have to research it. I snapped a photo, and we continued our march.

After surviving the Wellsvilles, I searched and discovered that we had observed a Jerusalem Cricket. Information on these insects is almost as scarce as a cricket sighting itself, so I decided to talk to someone with more experience.

Doctor James Pitt, an entomologist at Utah State who studies mathematical population models of various insect species, assured me that not only is the Jerusalem Cricket not from Jerusalem, it’s not even a cricket. Maybe my Martian bug idea was not too far off!

And while I thought its large and exotic, bee-like appearance signified danger, Dr. Pitt said that it was probably harmless unless provoked into a bite. I gathered from him that it was not prone to the large scale booms and busts of other locust-type insects—it was not even of the same family as those swarming pests. Instead, this is a bug that lives fairly solitary life cycles, mainly staying underground and only coming up occasionally. It seems as though our daytime sighting, and up in this high mountain environment of rocks and little vegetation, was somewhat rare. How did that cricket end up in such a place?

I decided to keep researching. Facts about females cannibalizing the males after mating or being known for feeding on potatoes did little to explain its presence on this high point (unless we were looking at a male determined to live a hermit-like bachelor life?). Besides, there were no potatoes on the Wellsvilles, and even the potato farmers I talked to were just as curious about this insect as I was. Chalk up another tally for Martian origins!

Still, I was not ready to give up. The more I learned, the more clear it was that, as foreign as the Jerusalem Cricket was to our modern heritage, some cultures with deeper roots in the region are much more familiar with it. Native Americans, ranging from the Yuma to the Navajo to the Hopi all included legends associated with the Jerusalem Cricket. I realized that my ignorance of them might have had more to do with what one article mentioned: urban development and roads tend to hamper these soil-burrowing and wingless bugs more than other, more mobile insects, limiting their range and visibility to people like us.

Thinking back to the moment my kids and I crowded around the Jerusalem Cricket, I started to feel as if the alien nature of this close encounter had more to do with us than the cricket. Perhaps we had something to learn from this subtle but persevering veteran of the West.

While learning about the Jerusalem Cricket helped provide me with this important perspective, it still did not reveal the mystery of what this particular cricket was doing way up on the Wellsville Mountain Range.

I just about gave up on making sense of the cricket’s location—hadn’t I learned enough by now? However, I thought I would read one more academic work before wrapping up. I discovered that the Hopi created figurines and masks of the Jerusalem Cricket for rituals, and they equated it with certain human-like traits. To them, the cricket represented human runners or racers, particularly over long distances. This was more in relation to their ceremonies, since Jerusalem Crickets barely achieve more than a crawl at the best of times, but the comparison stuck out strongly to me.

My mind went back to the Wellsvilles Ridge. I remembered that, when I was still very young, my dad participated in a Wellsville Ridge Race—a long distance run that went from one end of the Wellsvilles to the other. He would later go on to be the Cross Country Coach at Utah State for decades and just before he passed away over ten years ago, Utah State named their distance course after him and my mom: The Steve & Dona Reeder Cross Country Course. He is a distance running icon.

What was the Jerusalem Cricket doing up there? Something in me now thinks that perhaps the Wellsvilles are a place where distance runners go to dispense wisdom and perspective. I am glad that on the high slopes of the Wellsville Mountains, I got to have one of those runners give me wisdom for living life respectfully and responsibly. And I am glad to later meet another “runner” that offered perspective on the long legacy and hardy endurance of the wildlife that surrounds us.

I am Marty Reeder and my kids and I, and I’d like to think my dad, are all Wild About Utah.

Don’t Move a Mussel

You’ve heard the phrases, “Don’t move a mussel,” (spelled m-u-s-s-e-l) and “Stop aquatic hitch hikers.” If you have ever transported a watercraft, ranging in size from a paddle board to wake surf boat, you’ve probably been annoyed by the inconvenience of stopping at mandatory boat check stations for invasive species watercraft inspections. The threat is real and I hope this segment will make you a believer in inspection stations.

Let’s backtrack.

The opening of the St. Lawrence Seaway in 1959 allowed cargo ships to bypass the rapids on the St. Lawrence River and enter Lake Ontario. From there ships could access Canada’s Welland Canal, which also uses a series of locks to allow ships and barges to bypass Niagara Falls and access the rest of the Great Lakes. Proponents of the St. Lawrence Seaway sold the project on the grounds that it would turn the Great Lakes into a North American “Mediterranean” by transforming cities from Rochester, New York to Duluth, Minnesota into global ports.

They got what they wished for, but with a twist. “Salties,” or oceangoing cargo ships, traveling from the Mediterranean, Black, and Caspian Seas, emptied their ballast tanks in Great Lakes ports as cargo was loaded. In June of 1988 the first documented zebra mussel was found in Lake St. Clair—a small lake (in comparison to the Great Lakes) where the St. Clair River pools about halfway along its journey from Lake Huron to Lake Eire. This single, fingernail-sized mussel signaled a catastrophe. By the end of 1989, invasive zebra and quagga mussels were found in all five Great Lakes.

Zebra and quagga mussels are mollusks—soft-bodied invertebrates housed in hinged, two-part shells. They contain a muscular “foot” that allows them to move twelve to fourteen inches per hour—but that’s not how they travel most efficiently. Zebra and quagga mussels can produce a million eggs per year, that hatch into microscopic “veligers” which can swim efficiently for several weeks before their shell begins to form, sinking them to the bottom. Once a mature zebra mussel finds a suitable place for a home, the foot forms an epoxy-like bond with hard surfaces, making them difficult and expensive to remove from ship hulls, water intake pipes, docks, locks, and hydro-electric power infrastructure.

Zebra mussels thrive in water less than about fifty feet deep and on hard surfaces. Quagga mussels thrive in soft lake bottoms in water as deep as 500 feet. Together these invasive mollusks wreak havoc on aquatic ecosystems where they are most vulnerable—the bottom of the food chain.

Razor sharp zebra and quagga mussels filter microscopic nutrients from the water, This makes lakes clearer, while stripping them of nutrients aquatic species depend upon. By 2009 phytoplankton levels in the Great Lakes were diminished by 90% compared to pre-mussel levels. Clearer water makes for easier fishing for predatory birds and clearer water allows sunlight to penetrate deeper into lakes, warming them up faster and creating prime conditions for toxic algae blooms. Algae blooms deplete the water of oxygen and create ideal conditions for botulism, which then causes massive waterfowl die-offs. All of this has happened in the Great Lakes in a viscous cycle set in motion by zebra and quagga mussels.

Invasive mussels were found in Lake Mead in 2007 and in Lake Powell in 2013—transported from the Midwest recreational boats. What has happened in the Great Lakes can—and is—happening in the west.

So, the next time you have to wait in line at a boat-check station, know you are doing the right thing. Clean, drain, and dry your paddle boards, kayaks, whitewater rafts, fishing boats, and wake surfers before transporting them to other waterways and lakes. It only takes one contaminated watercraft to put the rest of the lakes and rivers that we all love in peril.

Songbirds migrate at night to avoid predators, air turbulence, and daytime heat. Down here on the ground we are unaware of the miraculous and essential voyagers flying up to 10,000 feet above us, but thanks to dedicated scientists collaborating for years on end we have free access to the data and graphs of these massive population shifts. The BirdCast Dashboard uses weather radar to track bird migrations, providing real time data showing peak migrations at the website dashboard.birdcast.info.

Did you know that World Migratory Bird Day is celebrated in May and October? Those are the peak months for spring and fall migrations, and the magnitudes of those flocks are considerable. Two thirds of songbirds migrate at night, and on the evening of Sunday, May 15, 2022, one million one hundred and fifty one thousand five hundred (1,151,500) birds crossed Cache County, Utah! Yes, 1,151,500 birds crossed Cache County, Utah, in one night!

It’s important to know when migrations are occurring because skyglow from artificial lighting causes bird disorientation and millions of bird fatalities each and every year. The declining bird population is problematic for many reasons, not least of which because some of the most intrepid travelers like the three-inch-long Rufous Hummingbird, which travels 3,900 miles each way from Alaska to Mexico, are keystone species with ecosystem services such as pollination and consumption of pests such as aphids and mosquitoes.

The Bobolink travels 12,500 miles to and from southern South America every year – those imperiled birds breeding at the west end of Logan may travel the equivalent of 4 or 5 times around the circumference of the earth throughout their lifetime. They come to Cache Valley for the habitat, stay to raise their young, and then head back to their distant winter feeding grounds.

A few top-notch steps toward bird-friendly living include the prevention of light trespass and skyglow, especially from 11 p.m. to 6 a.m., March – May, and August – October. Close curtains to prevent the indoor light from escaping, and avoid blue light outdoors – choose warm white or amber lights, and shield light bulbs to direct light downward. Motion-activated light bulbs are a great way to safely light the way while cutting down on unnecessary outdoor lighting, especially since there’s no clear scientific evidence that outdoor lighting reduces crime. Excess light, on the other hand, is a crime, and light trespass is an enforceable infraction. Light pollution is harmful to humans and deadly for birds.

Logan Mayor Holly Daines signed a Proclamation to Dim the Lights for Birds at Night because reducing skyglow and light trespass saves energy and birds by reducing the often fatal disorientation caused by artificial light.

Dark Skies are filled with bright stars, so by jingles, what say we all “Dim the lights for birds at night!

Mollusks in Utah, then and now

For many people in northern Utah, there’s nothing better than a warm afternoon with family and friends at Bear Lake. You can splash in the shallows, bask in the sunshine, and stroll along the shoreline while marveling at a centuries-old legacy of ancient mollusks.

Wait, what??! Ancient mollusks, 800 miles from the ocean? Yes, it’s true.

For years, when visiting Bear Lake, I’d be fascinated by snail shells strewn along the shore just above the waterline. I always wondered why we could find thousands of shells but would never see a live snail.

Mollusk shells along the southwest shore of Bear Lake, Rich County.
Well, it turns out that Utah is home to numerous species of live snails, but the shells we see beside Bear Lake have been there for nearly 10,000 years! They’ve lasted this long because they’re preserved by the calcium chemistry of a lake that’s fed by springs and groundwater beneath the limestone crags of the Bear River Range. Many years ago, researchers from the Smithsonian Institution identified six species of snail and one species of clam amongst the Bear Lake sands, all of which thrived in a bygone era when the lake was 30 to 50 feet higher and much bigger.

The snails that occupied those shells may have died out, but they have living relatives today. Scientists say that the group of invertebrates in the phylum Mollusca includes more than 85,000 recognized species, including clams and oysters, barnacles and limpets, snails and slugs, squids and octopuses. Some can even be found in our arid, landlocked state of Utah.

If you travel the highways of Utah and surrounding states, you’ve seen signs warning against a mollusk species that we don’t want in the state: the quagga mussel. These clam-like creatures have turned up in Lake Powell and we don’t want them in other lakes and reservoirs. They’ve become a nuisance in other states, clogging pipes and water lines, and competing with native fish for food. Once they become established, removing quagga mussels or the closely related zebra mussel can cost many millions of dollars. That’s why Utah has set up boat-inspection stations across the state to try to keep them out.

Another mollusk that many people would like to be rid of is the common garden slug – also called the grey field slug and known to malacologists as Deroceras reticulatum. Slugs don’t seem much like oysters or squids, but they’re basically just snails that have evolved to get along without a shell.

Less visible are the many other species of mollusks found in our state. A few years ago, biologist Eric Wagner published the Utah Mollusk Identification Guide with descriptions of 139 species of snails, slugs, clams, and mussels found within the borders of our state. Just one year later, Eric and a colleague, Christy Bills from the Natural History Museum of Utah, published an article reporting three additional species – two snails and a slug – that had not been seen in Utah before. Undoubtedly there are more that no one has noticed yet.

Just about all of Utah’s mollusks are cryptic – a term biologists use to refer to creatures that are hard to notice. Many are quite rare. One example is the Kanab ambersnail, a dime-sized creature found only at a large spring in Grand Canyon National Park and some small ponds near the town of Kanab, Utah. Others, like the freshwater mussel called the Western Pearlshell, can be found across the West but their populations are declining.

These creatures may not be obvious, but they’re part of what makes Utah’s wild nature so varied and wonderful. Losing any one of them would be a tragedy.

I’m Mark Brunson, and I’m wild about Utah’s wild creatures, no matter how cryptic.
