Least skipper is a tiny butterfly about the size of a dime. They have a fluttery, weak flight, but they are pretty easy to disturb, so they are a tricky subject. I find them in grasses near wet areas.
Happily I found a couple of them recently on a cool cloudy day – they weren’t flighty at all. I could rearrange grasses around them without them flying away, even move the tripod in closer in the thick waist-high grasses.
