Illinois is home to a number of large moths known as imperial moths or silkmoths. These moths are mostly nocturnal insects of forests, so they're not observed as much as their relatives that are active during the day—butterflies and skippers. However, silkmoths can occasionally be spotted around lights in the evening. Here's a short video featuring nine of these nocturnal beauties.
