ooh nice. Nature makes a lot of big green caterpillars, but I second your ID. I think the stack looks good, but sometimes they won’t sit still for more shots and I’d be happy with this if it were mine. You could darken the leaves in the ULC as well, just to make the critter stand out more. A really nice catch.
Oh, yes, Allen, very nicely done. I agree with Kris on darkening those leaves in the ULC, but even as presented it is an excellent image. Great find and capture.
