I chased butterflies and other insects along the gravel road near my house yesterday, and came across a hackberry emperor, Asterocampa celtis. Hackberry butterflies are active little butterflies that are hard to sneak up on to photograph. But they are fun anyway.
I spent some time trying to get close enough to this one to take a good picture but had no luck. It would land briefly then dart away when I got close. But about the time I was ready to give up it landed on me. I was able to coax it on to my finger so I could get a better shot.
Of all the butterflies found in Iowa, the hackberry is the most likely to land on you.
I love hackberries.
