I’m not really an expert on butterflies. But while hiking recently in the Front Range foothills , I saw so many of such varied species that I had to check into them a bit more. All these different butterflies are from just one hike.
Females lay single eggs near violets. Caterpillars do not feed, but overwinter until spring, when they eat young leaves of violets.
These two photos show two species of fritillary butterflies. They tend to be orange with black squiggles.
I haven’t found anything talking about this, but every time I saw this female Common Wood Nymph land, she seemed to lay her wings onto the landing surface. In late summer, females lay eggs singly on host plant leaves. Caterpillars hatch but do not feed, instead hibernating until spring. (Butterflies and Moths of North America)
Skippers are a type of butterfly I had never noticed before I started taking pictures of everything of interest on my hikes.
Males may defend their territory. (Butterflies and Moths of North America)
I used two websites to learn about butterflies: Butterflies and Moths of North America and Colorado Front Range Butterflies. Both are very cool, but the first has an interactive map where people can post their sightings and photographs of the moths and butterflies they see.
