In Kenya, there lives a spider that drinks human blood. But fear not – Evarcha culicivora is an indirect vampire. It’s after mosquitoes that have fed on mammal blood. Evarcha specifically targets malarial mosquitoes that have just fed on blood, and it can tell them apart from other similar insects using its keen senses of vision and smell. Evarcha also sniffs its way to places where mosquitoes are likely to gather and it’s bizarrely drawn to the smell of human feet. Once it feeds, the blood doesn’t just nourish the spider – it’s also an aphrodisiac. After feeding on mosquitoes, Evarcha smells sexier.
