Do grasshoppers have brains?
Publisher Summary. The central nervous system (CNS) of the grasshopper consists of a brain and a set of segmental ganglia that together make up the ventral nerve cord. Each ventral nerve cord ganglion develops very similarly during early embryogenesis.
What is the ratio of males to females in crickets?
Whether you’re raising crickets as pets or as food for your other pets, you might wonder about the ratio of males to females to maximize the production of offspring. Cricket sex is easy to tell by the number of appendages extending out from the abdomen. Males have two, and females have three.
