Katydids get their name from the perceived sound they make. Their repetitive clicks and calls sounded like someone saying, "Ka-ty-did", so the common name became that phrase. Both genders are capable of producing the sound. Katydids are related to crickets and grasshoppers, with large back legs for jumping. They have wings, however, and will fly away from danger.

Adults are remarkably well-camouflaged for sitting on trees. Their body resembles a green leaf, even down to a detailed venation (veins in the leaf). Katydids will remain very still when on alert, but will quickly fly away when threatened, scared or disturbed. Nymphs (juveniles) have spots or speckles of black on them and eventually mature to the complete green color.

Angle-winged katydids lay their eggs on twigs in a single row, one slightly overlapping the egg before it. The eggs are flat, almost like small pumpkin seeds, and they may might not all be the same color.

Katydids eat the leaves from the tops of trees and bushes, where there may be fewer predators and less competition. They can be found in parks, gardens, fields and woods. Adults are most active in summer and autumn, but in Florida, the warm weather allows them to remain active all year long.
