These species
are commonly known as katydids or long-horned grasshoppers and are
recognisable by their slender, often leaf shaped wings that are
held roof-like over the body. Most species are green or at least
partly so and can be distinguished from other grasshoppers (Acrididae)
by their very long antennae. Most species are plant feeders although
some may predate other insects.
Many
katydids are nocturnal and rest during the day, well camouflaged on vegetation.
Many species have developed colours and shapes to resemble their daytime
resting places and are more easily found at night by locating the direction
of their calls. Katydids have special structures on their wings that produce
sound when rasped together. Katydids have large hind legs for jumping
but tend to either walk or fly rather than hop around like other members
of this order such as grasshoppers or crickets.
