This is a question I’ve been trying to answer for a while now, with most search results giving me the answer to the smallest insectivorous mammal. But surely there’s a tiny little insect or arachnid that feasts upon even smaller insects? Or perhaps a weasel of the arthropod world that hunts insects larger than it?
