Moths are generally nocturnal but Dianne Machesney found this one, a Chickweed Geometer Moth, during the day at Hillman State Park.
So how can you tell it’s a moth?
Look at the antennae, so fuzzy with many tiny branches. Moths generally have feathery antennae; butterflies have smooth ones with little knobs at the end.
Of course, there are exceptions. The moth link, above, explains that male Chickweed Geometer moths have very feathery antennae while the females’ are thread-like. It’s easy to tell this moth is a boy.
For more information on the differences between moths and butterflies, see this excellent guide by Chuck Tague.
