English: WE ARE THE GREAT MIMICRY ARTIST IN THE WORLD HISTORY The oblong-winged katydid, Amblycorypha oblongifolia (De Geer, 1773), is a false katydid in the subfamily Phaneropterinae. It is very similar in appearance to Amblycorypha floridana, the Florida false katydid; however, the two species can be differentiated by their calling songs and distribution. The false katydid adults are distinguishable from the adults of the true katydids (subfamily Pseudophyllinae) by their hind wings that extend beyond their leathery forewings. True katydids have relatively shorter forewings, and, compared to those of the false katydids, the wings bulge out at the sides. The nymphs resemble the adults, except that the abdomen is rounder and they lack wings or sexual characteristics. As the nymphs molt, they develop wing pads. The wings are not fully formed until sexual maturity is reached, which takes about two months. The eggs are deposited in soil and, depending on the location, can take two or more years to hatch. In captivity, the Audubon Butterfly Garden and Insectarium has recorded that males from the same cohort hatch before the females.
