"Yes, even tiny insects have brains, though the insect brain doesn't play as important a role as human brains do. In fact, an insect can live for several days without a head, assuming it doesn't lose a lethal amount of hemolymph upon decapitation.
"The insect brain resides in the head, located dorsally. It consists of three pairs of lobes. These lobes are fused ganglia, clusters of neurons that process sensory information. Each lobe controls different activities or functions.
"Other ganglia throughout its body control most of the overt behaviors we observe in insects. Thoracic ganglia control locomotion, and abdominal ganglia control reproduction and other functions of the abdomen. The subesophageal ganglion, just below the brain, controls the mouthparts, salivary glands, and movements of the neck.
"The insect brain actually controls only a small subset of functions required for an insect to live. The stomodaeal nervous system and other ganglia can control most body functions independent of the brain."
Isn't it amazing how God created even the tiniest of animals so complex and perfect!Source(s): http://insects.about.com/od/morphology/f/Do-Insect... I love insects!!

They do have brains, but it is puny compared to ours. Nevertheless, insects like honey bees have very sophisticated ways to navigate the world, and to communicate where food may be using their waggle dances. Somehow those tiny brains figured out how to build bee hives with the least amount of building material possible. Those tiny brains can do a lot.

The insectan frightened system developed from the segmented method of annelid worms, such as the earthworm. Every of the insect's segments has its own nerve core, referred to as a ganglion, which is hooked up with the aid of a pair of nerves to the ganglia of the adjoining segments. The insect's head includes a set of fused segments; when you look intently on the head pill of a grasshopper you will see that one of the most sutures between the segments. Inside the head, the segmental ganglia have fused to form a mind
