Dicopomorpha echmepterygis is a species of fairyfly found in Illinois, United States. As of 2020, it is the smallest known insect species.


D. echmepterygis are a species of parasitoid idiobiont that exhibit strong sexual dimorphism. Females have an average boy length of 550 μm, but males only have a length 40% of the females, instead having a body length between 139 to 240 μm, averaging 186 μm. Males are in fact smaller than certain species of single-celled amoebas and paramecia. Males are blind and wingless, and never leave the egg, which are laid on the eggs of the barklouse Echmepteryx hageni. Each egg contains at least one male and one female, though around 1/5th have a 3:1 male/female ratio.

This action is similar to other members of the chalcid wasps like Prestwichia aquatica.
