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.
