There was entomological excitement and sadness today as I found a caterpillar that I’d never seen before…in our pond. It looked like a 3rd or 4th instar (out of 5) of the Imperial moth (Eacles imperialis). I’ve never seen this moth in our area before-surrounding states and south, yes, but not Illinois. And to have one in my own yard is amazing! They eat a variety of trees including oak, pine, maple and sweetgum. I’m pretty sure this one dropped off the oak tree which hangs over the pond. Hopefully there are a couple more caterpillars hanging out somewhere in those big trees.
