Do insects have blood and do they bleed when they get hurt?
Yes, insects have blood, but it’s not like human blood. Human blood is used to carry oxygen throughout our bodies and is red because of the hemoglobin in it. In insects, blood is used to carry nutrients throughout their bodies, but not oxygen. Oxygen comes through a system of air tubes that connect to the outside through openings called spiracles. Insects do bleed when they are hurt and their blood clots, like a human’s, so a minor wound will usually heal.
