Do ladybugs have a heart?
The abdomen section of the dorsal vessel is considered the insect’s heart because it has muscles and ostia, openings that allow hemolymph to enter and exit. Hemolymph enters the heart when it’s relaxed. The heart then contracts and pumps the hemolymph through the vessel toward the insect’s head.
