Batfly

It's an ant! It's a spider. No—it's BATFLY! A blind, wingless species of fly that lives on and with New Zealand short-tailed bats in strange symbiotic relationship. Similar animals infesting bats in South America and elsewhere are blood-sucking parasites—the vampire's vampire—but the New Zealand version is a vegetarian coprophage specialising in the management of bat guano.
