Insectivore

A species or an organism that eats insects or invertebrates.

Examples
Examples of insectivores include nightingales, aardwolfs, echidnas, swallows, anteaters, carp, frogs, lizards, bats, and spiders. Even large mammals are recorded as eating insects; the sloth bear is perhaps the largest insectivore. Insects also can be insectivores; examples are dragonflies, hornets, ladybugs, and praying mantises. Insectivory also features to various degrees amongst primates, such as marmosets, tamarins, tarsiers, galagos and aye-aye. There is some suggestion that the earliest primates were nocturnal, arboreal insectivores.
