👉 The term "hematophagous" is typically used to describe organisms that feed on blood. This includes all types of insects, such as mosquitoes and flies, as well as some higher-order invertebrates like beetles and spiders. Hematophagous organisms are often associated with the consumption of blood or other bodily fluids, and they may exhibit a range of behaviors including feeding, behavior modification, and even aggression towards living hosts if their diet is insufficient.
