 Moths usually rest with their wings spread out to their sides.Butterflies frequently fold their wings above their backs when they are perched although they will occasionally "bask" with their wings spread for short periods (several types of Swallowtail butterflies tend to frequently rest with their wings spread when in sunlight).However, some butterflies, like the skippers, may hold their wings either flat, or folded, or even in-between (the so-called "jet plane" position) when perched.
