Oblong-winged katydid

The males often perch on tall plants to sing. They stridulate in the early evening hours once the light fades, rarely after midnight.

They produce their song by rubbing together the base of the two forewings. The stridulatory peg on one wing slides across the “bow” of the other wing.

The sound is highly recognizable, a loud, quick, repeated “zi-zit.”

The tympanal organs at the base of the tibia on the forelegs allow both sexes of katydids to hear the song. 

These insects belong to the Phaneropterinae subfamily, which includes several genera.

Des organes tympaniques situés sur les pattes avant, à la base du tibia, permettent aux scuddéries des deux sexes d’entendre leur chant.

Cet insecte fait partie de la sous-famille des Phaneropterinae qui regroupe plusieurs genres.
