I found this wacky-looking grasshopper nymph the other day. It's one of the genus Truxaloides, also known as stick grasshoppers. It is getting adult coloring but has yet to get an adult-sized set of wings. Although grasshopper heads don't contain too many brains, I can't help but think that this one is somehow brainless or something. Love those big mad eyes, though.
In fact, a grasshopper's brain is located between its eyes, just above the esophagus. The brain is connected to the 1st ventral ganglion by a pair of ventral nerves that surround the gut. A grasshopper can do many things, like walking and jumping, without its brain.
