Why don’t bugs bleed red when they explode on my windshield?
Bugs don't have blood. Bugs have hemolymph. Hemolymph serves as both blood and the other fluid that surrounds cells in our bodies.
The Short Answer
Bugs don't have blood. Bugs have hemolymph. Hemolymph serves as both blood and the other fluid that surrounds cells in our bodies. The color difference comes from the molecule that binds to oxygen. Blood contains hemoglobin, an iron-based protein that binds to oxygen. Hemolymph contains hemocyanin, which is copper-based. When we bleed large arthropods like [horseshoe crabs](_URL_0_) we can see that hemocyanin gives the the hemolymph a blue, not a red color. Not as noticeable when you squash bugs because other tissues are mixed in with the hemolymph.
