Tachinid Fly
A bristly, house-fly-like insect that looks unremarkable at a glance but hides one of the most important ecological roles among flies: its larvae develop as internal parasites of caterpillars, beetles, and other insects, quietly regulating populations across the landscape. Gardeners often welcome tachinid flies as natural allies against crop-damaging pests.
flyOgre-faced Spider
A twig-like nocturnal spider with enormous, light-gathering eyes that weaves a small rectangular net and hurls it over passing prey in a lightning-fast ambush.
