In which months of the year are there katydids?

In July, there are katydids in spring, but they cannot chirp at that time. They have to wait until July for them to become adults and chirp.

The katydid is an insect of the family Katydids, mainly distributed in Hebei, Henan, Jiangsu, etc. The body of the katydid is flat or cylindrical, and the antennae are generally longer than the body.

Wings may be well developed, underdeveloped or absent. Male winged individuals have a sound organ near the front wings, which produces sound by rubbing the left and right wings together. The katydid has well-developed jumping hind legs. When in danger, it is their way of self-preservation to jump quickly to avoid the enemy. Protective color is also a self-defense trick of the katydid. Since the body color of katydids is almost all green or brown, and some of them can mimic leaves or dead leaves, it is difficult for natural enemies to find their whereabouts at a glance when they are not singing. The katydid is the leader of the three major singing insects. A female katydid can produce more than 200-450 eggs.
