Mosquitoes typically do not bite leeches. Mosquitoes are known to feed on the blood of various animals, including mammals, birds, reptiles, amphibians, and even some fish, but leeches are not a common target for them. Leeches themselves are blood-sucking creatures, but they feed on vertebrate animals, not on other invertebrates like mosquitoes.

The feeding habits of mosquitoes and leeches are quite different, and there is no known ecological interaction where mosquitoes would feed on leeches. Mosquitoes use their proboscis to pierce the skin and suck blood, while leeches use their suckers and teeth to attach to their hosts and feed on blood.
