orthopterous (adj.)

by 1815, "belonging to the order Orthoptera;" literally "straight-winged," that is, "having wings that lie straight when folded," from Modern Latin orthopterus, from Greek orthopteros "having straight (upright) wings or feathers," from orthos "straight" (see ortho-) + pteron "wing" (from PIE root *pet- "to rush, to fly"). Orthoptera is the name proposed in 1789 for the order of straight-winged insects, including cockroaches, mantises, grasshoppers, crickets, katydids, and true locusts.
