Butterfly season appears to be starting too. It will still be a while before monarchs return and silkmoths and swallowtails hatch. But I saw viceroy caterpillars out of their hibernacula, had some commas and red admirals in my butterfly trap, and saw lots of little webs of eastern tent caterpillars. These annoy people, but are actually native and seldom kill trees as they mature in plenty of time for trees to leaf back out after being defoliated by the little buggers.
