Vampirism — piercing or cutting animal skin to suck or lap up blood — is known throughout the animal kingdom. Mosquitoes come to mind, plus ticks, mites, vampire bats, and the vampire finch of the Galapagos Islands. But … vampire moths? Yes indeed, there are moths that feed on the blood of vertebrates, including humans.
People who find insects to be creepy usually do not have a problem with moths as they move slowly and do not bite. All that they generally do is flying around the light.
But it is a myth that all moths are harmless.
This species of moth that lives in the dense jungles of South America are highly creepy.
