Tinkerbella thankfully does not bother humans, although it is a parasite on the eggs of other insects. Researchers found it after conducting a meticulous search of species in a forest located at Alajuela, Costa Rica. Magnification was needed to identify the mysterious Tinkerbella.
Another very fairy-like feature of this insect is that its tiny, fringed wings flap at several hundred beats per second.

Regarding Tinkerbella‘s minute size, and the quest to find other small species, lead author John Huber from Natural Resources Canada wrote, "If something is physically possible in living things, some individuals of at least one species, extinct or extant, will likely have achieved it. So the lower size limit, by whatever measure of size is chosen, was almost certainly already evolved-somewhere, sometime. If we have not already found them, we must surely be close to discovering the smallest insects and other arthropods."
Time will tell if he's right. We might also have to develop even more powerful magnification tools to see if we're really identifying all of the tiny insects and related organisms that exist in the world.
