Katydids are making their evening presence known by their characteristic "katydid" sound. It is as if they were saying, "Katy did, she didn't, she did" over and over again. The sound has a very raspy quality to it and that is because it is truly a rasping sound - something rough rubbing over something smooth.
In late August, the warm nights are filled with the sounds of crickets and katydids. Male katydids make their sound much like the black crickets do, by rubbing two wings together. One of the wing edges has a fine little rasp while the other is smooth. The females listen carefully. Their ears - located on their front legs - are dark colored flat discs that receive sound vibrations. Our ear drums do the same thing - they feel the sound vibrations all around us.

Look carefully at the front leg of this katydid. Notice a small brown spot about halfway up the leg. That is the Katydid's ear.

Katydids are not grasshoppers.
