The Common True Katydid is a robust, leaf-green insect with dome-shaped wings that blend perfectly with foliage; the name 'katydid' comes from the male's stridulating song, which sounds like a repeated 'katy-did katy-didn't.' These loud insects are almost never seen despite their deafening chorus on summer nights in eastern forests. They spend their lives in the treetops.
