Ask An Entomologist: Guoguo
November 23rd, 2008 by Kelley
What is the scientific difference between a grasshopper and a cricket? We live in Beijing and they have this “Guoguo” of giant grasshopper which makes a very significant sound. Please look it up at you tube they have a video.
Do grasshoppers and crickets hibernate?
Thanks Anita in Beijing

Well, to me, the Guoguo looks like a katydid and not a grasshopper. Grasshoppers, katydids and crickets all belong to the order Orthoptera, which has variable body size, chewing mouthparts, well-developed compound eyes, and most have 2 pair of wings. The orthoptera can then be divided into two groups, one which is the grasshoppers (Caelifera) and the other contains the katydids and crickets (Ensifera).
Grasshoppers have short antennae, short ovipositors, less than 3 segments on the tarsi and the tympana is found on the abdomen. Crickets and katydids have really long antenna, more than 3 segments on the tarsi, long, sword-shaped ovipositors, and the tympana found on the forelegs.
Whether they hibernate or not would depend on where and which species you are talking about. Generally though, no, the adults die when the freezing temperatures come and it is the eggs that over winter and then hatch in the late spring/summer.
