Katydids and Bush Crickets (Tettigoniidae)

 

The Tettigoniidae encompass 20 subfamilies, 1,070 genera, and over 6,400 species of orthopterans. They are found on all continents except Antarctica, but most diverse in the tropics, particularly in the Americas.  The majority are forest species, though others occur in grasslands, scrublands, or wetlands. Katydids have a thick body, long threadlike antennae, 4-segmented tarsi, tympana on the front tibiae, and a sickle- or sword-shaped ovipositor in the females. Wings are long, short, or nearly absent. The males use organs on the hind angles of their front wings to produce the continuous trills. Most species are medium in size (10-60 mm), although few are giants growing to 120-130 mm, e.g., with a wingspan of 25 cm. Katydids are usually green or brown, sometimes patterned to mimic discoloration of dead leaves. Most species feed on plant foliage, flowers, seeds, and pollen; others prey on insects and other invertebrates. Primarily nocturnal. Incomplete metamorphosis.
