Katydid

Insects in the family Tettigoniidae are commonly called katydids or bush-crickets. There are more than 6,400 species. Part of the suborder Ensifera, it is the only family in the superfamily Tettigonioidea.

Tettigoniids may be distinguished from the grasshopper by the length of their filamentous antennae, which may exceed their own body length, while grasshoppers' antennae are always relatively short and thickened.
