The circulatory system of insects is open, whereby blood, (haemolymph), flows freely through the body cavity, (haemocoel).
There is a dorsal vessel which is closed at the posterior end of the abdomen, and runs forward along the dorsal midline and opens in the head at the anterior portion, (aorta).
The insect heart.There are several chambers and openings, (ostia), along the dorsal vessel where blood enters it through valves. The blood is then pumped forward to the aorta and into the body cavity.

Yes, in fact, they do. I just did some research on it and they do actually have a heart. It's a tube that pumps colorless blood from the head back to the rear and then back to the head.

Insects have whats called a "Open Circulatory System" which means that the "blood" just sloshes around in there.
