A female Katydid, note the brownish ovipositor curling up from the end of the abdomen into the wings, rests on a palm frond along the South Oslo Riverfront Front scrub trail. This is possibly the common Fork-tailed Bush Katydid. Clearly visible on this Katydid’s front leg is the dark oval tympanum surrounded by red. This is the eardrum allowing the Katydid to hear sounds, especially mating calls, and there is a matching one on the other front leg.
