Smallest Insect:

Fairyflies are tiny wasps (family Mymaridae) that are probably the smallest of all insects.  In Dicopomorpha echmepterygis, a Costa Rican species that parasitizes the eggs of other insects, the males may be no more than 0.139 mm in length.  Their tiny bodies, neatly packaged with complete digestive, reproductive, respiratory, and circulatory systems are actually smaller than a single-celled paramecium.
