👉 Heartthrobs, also known as "heartbeats" or "heartbeaters," are a type of insect that feed on blood. They are commonly found in the human body and can be found all over the world, including in places like the Arctic, deserts, and even in urban areas. Heartthrobs are often seen as pests, but they have evolved to thrive in their environment by absorbing nutrients from the blood of other animals such as deer or humans.
