If you’ve listened to these Wild About Utah segments for a while, you’ll have noticed that we tend to focus on places where humans don’t live. But what we call “nature” can flourish almost anywhere, including the places where people dominate.

I’m an avid runner and walker. And my town has done a lot of street and sidewalk work this year, so I’ve spent a lot of time looking down to make sure I don’t suddenly trip or step in a hole. Earlier this year, I was looking down while walking to my office, and I was amazed by how many ant colonies I was seeing on the sidewalks. Each colony included hundreds of tiny ants, milling around in what looked like random patterns. Some blocks had an ant swarm every 20 to 30 feet.

I’d seen them before, of course, but hadn’t realized just how ubiquitous they are. Being a scientist and therefore endlessly curious, I began to wonder: What are these ants doing when they swarm? And how do they all know to do it at the same time?

The particular species of ant that I was seeing – and I’m sure most of us have seen them at one time or another – is called the immigrant pavement ant. In some places they’re also called sugar ants, thanks to their nasty habit of sneaking into people’s kitchens to find sweet things to eat. They’re tiny, 2.5 to 4 millimeters long, shorter than a grain of rice. Originally native to Europe, some of them probably stowed away on a ship to America in colonial times. Now they’re widespread across North America.

As I watched closely, I realized that the ants’ movements weren’t entirely random. They would approach another ant, stop for a half second, then move on. That’s because one purpose of swarming is colony expansion. They wander around checking each other out. If an interloper from another colony enters the swarm and is recognized as a stranger, it will be attacked. Sometimes hundreds of ants can die in battles between neighboring colonies.

The other thing that happens when they’re swarming is mating. Some of the ants develop wings and take nuptial flights, when males and queens from different colonies take to the air and mate. They like to do this on clear, warm surfaces, when the days are long and hot sunlight has warmed the soil for a while. If each colony responds to the same environmental cue, it means there is a huge pool of prospective mates, which increases genetic diversity and colony success.

After mating, the males die and the queens, which are about twice as big as the other ants, fly off to start new colonies. Worker ants from nearby colonies will collect and remove the dead ants quickly. This helps prevent predators from being able to locate the colonies, which spend most of their time in nests beneath flat stones or similar hard spaces – such as sidewalks. Within a week after the swarms appear, they’re gone.

Pavement ants can be a nuisance if they get into your pantry. But when they’re swarming safely out on the sidewalk, they’re just a fascinating part of nature – one that most of us can observe without going more than a block or two from home.

I’m Mark Brunson, and I’m wild about Utah’s natural creatures, wherever they’re found.

“Pavement ants (Formicidae, Tetramorium immigrans) are northern Utah’s most common pest ant in and around homes and structures. Until recently, the pavement ant’s scientific name was Tetramorium caespitum, but recent genetic work has clarified that our common pest Tetramorium species in the U.S. is from Europe and has been given the name T. immigrans (Wagner et al., 2017; Zhang et al., 2019). Genetic variation among pavement ant populations in the U.S. is low and it is believed that current populations were derived from one or a few closely related colonies from Europe introduced into the northeastern U.S. about 200 years ago (Wagner et al., 2017; Zhang et al., 2019).”

In late June of this year, we at Stokes Nature Center held our first pollinator camp. In this period, we worked with a local beekeepers, visited the USDA U.S. National Pollinating Insects Collection at Utah State University, and we fed hummingbirds from the palm of our hands. In spite of the short attention spans that summer brings, there were moments of pure uncut interest from the middle school age campers. Here, I’ll describe some bees and I want you to think if these would hold the attention of any teenagers in your life. Images of these bees and many more can be found online at the flikr page of the USGS bee lab, links to this page are online at WildAboutUtah.org and UPR.org

When I say fairy bee, what do you think of? Small? Adorned with jewels? The fairy bees of the genus Perdita are a group of very small bees, with the largest of them being just 10 mm long (or the length of two grains of rice put together end to end). The smallest bee on the earth, Perdita minima, or mini fairy bee is just 2mm-the width of a grain of rice. Though they may seem easy to miss, they are numerous and right under our noses. These fairy bees are one of the most common types of bees in desert ecosystems, like that of the Grand Staircase Escalante National Monument in Southern Utah. These bees are other-wordly, sometimes a blonde or light brown or dark with white metallic reflective markings perhaps like a jewel.

What about a blue bee? Do you know much about what pollinates your fruit trees? The Blue Orchard bee, Osmia lignaria, is a shiny blue bee that pollinates many fruit trees here in Utah including apple, apricot, almond, plum, cherry, peach, nectarine, and pear. They’re more efficient than the honeybee when it comes to fruit production per individual and there are great efforts to understand their future as a managed pollinator at the Pollinating Insect-Biology, Management, Systematics Research unit here in Logan UT.

Here’s my last marvel-the sweat bee. Have you ever noticed a small insect landing on you in the heat of day that might have been black, green, or green up top and striped on the bottom? This might be a sweat bee! This name sweat bee encompasses many types of bees-with 4,500 species in this group of all varieties of shapes, sizes, colors. One of my favorite for its fascinating clashing color combination is the bicolored striped sweat bee, Agapostemon virescens. This sweat bee has a green upper body reminiscent of a wicked green witch with a yellow or white and stripped lower body.

I could go on, as there are 21,000 species of bees each with their own outfits and lifestyles, with Utah being home to an estimated 1,100 species. But for now, I’ll leave you be.

Love nature? There’s an app for that

We hear a lot these days how people spend too much time with their electronic devices. The internet is full of advice on how to get kids away from their screens to enjoy nature, and that’s great. But for me, as someone who has always loved natural spaces, I’m finding that a screen can actually enhance my time outdoors.

My iPhone is packed with apps that help me connect to nature. One lets me identify birds by their song. Another recognizes constellations in the night sky. I’ve got several plant identification apps. But my favorite nature app is called iNaturalist. When I see a plant or animal in the wild, I can snap a photo, and the app’s artificial intelligence will help me identify what species I’m seeing. Then I can upload the photo and its GPS coordinates so others can see what I found and where I found it. In doing this, I help scientists learn where species are found and how common there are. And if the AI turns out to be wrong – which does happen – experts who use the app can tell me what they think I really saw.

I’m outdoors a lot, and I use iNaturalist a lot. It’s almost an obsession. But this obsession helps me learn to see nature in new ways. Here’s an example: Earlier this year, my wife and I were walking along a cattle trail near Canyonlands National Park. It was early May, and we were delighted to see wildflowers blooming in the desert. And of course, I took photos as we went. At one point, I happened to see a bright yellow, daisy- shaped flower with a red center. I knew it was a red dome blanketflower, closely related to the bright red and yellow Gaillardia plants that many Utahns grow in their waterwise gardens.

But when I knelt to take a closeup photo, I saw something I hadn’t noticed. Feeding on nectar from some of the flowers were small, brightly colored moths, their wings a deep red with white stripes in a pattern like a woven blanket, their heads a vivid orange. iNaturalist told me I’d found a group of painted schinia moths – a species I’d never encountered or even heard of before.

Intrigued, I wanted to know more. I learned there are at least five species of painted schinia moth in the U.S. Southwest, each of which feeds only on a particular kind of blanketflower. This sort of plant-insect specialization is common. It benefits the plants, because as moths move from flower to flower, they carry pollen with them, and a specialist pollinator won’t bring its pollen load to a species that can’t use it. And it benefits the insects. As they adapt to the unique chemical and physical features of their host plants, they can gather and use food most efficiently. And – as I learned when I had to look closely to even see my painted schinia moths – they can evolve to use camouflage to avoid predators.

Of course, the downside to specialization is that if something bad happens to the host plant, it also endangers their insect specialist. Luckily for the painted schinia moth, blanketflowers are abundant in late spring in the southeast Utah desert. That’s lucky for us humans, too, as we enjoy the brilliant color they bring to red rock country – even more so if we take time to kneel down, snap a photo, and examine them more closely.

Las luciérnagas encuentran el amor en Utah

Mi nombre es Kate, y me llamo Carlos, y hoy este Wild About Utah está en español e inglés. Esta historia también, se puede escuchar on line en UPR.org

Contra todo pronóstico, las luciérnagas encuentran el amor aquí en Utah. En lugares como el Parque de las Luciérnagas en Nibley, puedes ver estas deslumbrantes linternas bailar y rebotar a partir de principios de junio. Ver estas luciérnagas es mágico, aún más cuando sabes lo que les costó brillar cada noche.

El primer desafío que enfrenta una luciérnaga es encontrar un buen hábitat húmedo aquí en el árido Utah. Encontrar un hábitat oscuro y húmedo puede ser difícil, pero de alguna manera las luciérnagas lo han logrado y lo han hecho en Utah desde posiblemente 1929. Una vez que una luciérnaga encuentra un buen lugar, ahora tienen que encontrarse entre sí. Hacer esto requiere precisión y química. En su linterna abdominal, la enzima luciferasa debe abrazar tanto la luciferina como una molécula de energía estrechamente para ayudar a combinar sus partes.

Luego, la luciferina se combina con oxígeno para formar la energética oxiluciferasa. Al igual que un niño con demasiados dulces, la oxiluciferasa ahora está desesperada por liberar algo de energía antes de que sea demasiada. Esto lo hace liberando un fotón que emite luz y vemos la magia ante nuestros ojos. Como si crear luz dentro del cuerpo no fuera suficiente, ahora deben ajustar su señal a su especie y encontrarse entre sí. Cada especie tiene un código morse único de luz que necesitan parpadear para encontrarse.

Ahora, digamos que una luciérnaga llega a un hábitat pantanoso y conoce al amor de su corta vida de 3 semanas, ahora puede comenzar el romance. Los machos y hembras copulan durante horas, permaneciendo quietos y pegados de extremo a extremo. Durante este tiempo, el macho le da a la hembra lo que se llama un regalo nupcial lleno de proteínas junto con su esperma. ¡Si eso no es romántico, no sé qué lo es!

Las hembras almacenarán este regalo y lo digerirán durante varios días para ayudarla a obtener las proteínas necesarias para poner sus huevos. Una vez puestos, estos huevos tardarán entre unos pocos meses a 2 años en convertirse en adultos, donde iluminarán su corazón para repetir el proceso.

Para mi entender la naturaleza y los pequeños detalles de ella me llena de satisfacción, el saber que es tan perfecta. Esa pequeña luz llena esperanza, nos muestra que el mañana sera mejor.

Mi nombre es Kate y me llamo Carlos y estamos locos por Utah.
