Fairyfly Wasp
The smallest known insect in the world at just 0.139 mm in length. Males are blind, wingless, and smaller than some single-celled organisms.
Did You Know?
Males of this species are smaller than a paramecium — they are blind and wingless, existing solely to mate with sisters before they even leave the host egg.
Big-eyed Ground Beetle
A small, fast-running ground beetle with enormously enlarged eyes relative to its body size. It has a bronze sheen and is a visual hunter that chases springtails across the ground.
Did You Know?
Its eyes are so large relative to its head that they are considered one of the most extreme examples of visual adaptation among ground beetles, rivaling tiger beetles.
