What is the smallest insect in the world?

    The smallest insects are fairy flies, which are insects that parasitize other insects’ eggs by laying their eggs inside them. Fairy flies are only 1/5 of a millimeter in length. Many beetles are less than one millimeter in length, and the North American Feather-winged Beetle Nanosella fungi, at 0.25mm, is a serious contender for the title of smallest insect in the world.

    Fairyflies are considered to be the smallest insect known in existence. The fairyflies are tiny wasps from the Mymaridae family.

    The Costa Rican fairyflies males are no larger than .0139 mm in length. Many of these fairyflies are only about .5 to 1 mm in length and there have even been some found to be no larger than 0.2 mm. This means it was only 0.008 of an inch.

    It would take a microscope to see these tiny wasps.
