Animals are known to occasionally exploit novel food sources. And sometimes those food sources are human blood. And sometimes those animals are moths.
What’s really fun about this is that they’re not the first species of vampire moth discovered. A similar species was found in Malaysia in the 1970’s.
Maybe if they turn into a problem we can sic Evarcha culicivora on them. It’s a jumping spider from East Africa that hunts mosquitoes, specifically targeting ones that have just fed on human blood. It’s not because they’re easy targets, the researchers believe that it’s because the spiders also really like human blood, they just can’t get it themselves (their mouths are the wrong shape). Apparently we’re just delicious.
At least we’re safe from vampire birds. They only prey on their own kind.
