Polyancsitrus cf. serrulatus (Katydid) This insect is a member of a tribe of flightless katydids that is endemic to the Caribbean, primarily to Hispaniola. It has some 20+ flightless species in which both sexes make calls. The katydids are a large, morphologically diverse group that can be found in most areas of the world. Most katydids are a characteristic bright green color, but there is huge variation between (and sometimes in even within) species. All are herbivores, but some will occasionally eat other insects as well. Katydids will eat leaves, seeds, fruits, and flowers. Like the crickets (to which they are closely related), they produce sound by rubbing one front wing over the other. While usually found in open areas, some live on trees and are able to make their living in forested areas. (Photo and info courtesy of Brian Farrell and the Harvard course on Caribbean Insects)
