They do, but they are very simplistic. They do not handle emotion, complex thought (at least for most species) or even pain (in most of them).
insects do have a brain. they use it differently then us.
They have their antennaes and their brain
no there isn't lool
most insects have a rudimentary brain that can respond to stimuli, but with very little reasoning
A spider and an Insect have legs,heads,brain,lungs...
The ant Ants and Honeybees are considered the most intelligent of insects.
Short answer: jellyfish or various small insects. If you want a deeper answer, it depends on what you call a brain because a jellyfish has a nerve cluster which is technically a giant brain and the insects without brains have what we call: ganglia it is basically a brain just with no ability to think abstractly; it just controls basic functions and instincts.
Yes, every animal has some sort of brain. Even jellyfish have nerve clusters that act as a brain. Some small insects have ganglia that control essential autonomic functions and movement.
No. First, the brain and ears do not connect. Second, insects do not eat human brains. NOTE: Parasites in the intestines can have eggs travel through the bloodstream and by that route get into the brain.
Mosquitoes like other insects have a tiny central nervous system which consists of a nerve ganglion rather than an actual brain. A ganglion can be considered to be equivalent to a very tiny brain.

Bees have one of the largest brains among insects. Their brains have nearly a million neurons, compared with about a billion in a human brain.
