Katydid Pictures, Pictures of Katydids

Pictures of four different species of Katydid. Katydid are closely related to grasshoppers.

These large, usually winged insects are related to grasshoppers and crickets. Males use special sound-producing structures on their wings to sing to attract mates. Females often chirp in response, which some people thinks sounds like "Katy did, katy did"--giving them their name.Most Katydids are shaped like colored leaves, but sometimes the genes of a specific species (such as the Oblong-winged Katydid shown here) create unusual coloration.
