Termidote

Termidotes were a type of tiny creature found on the forest moon Endor. They possessed six limbs, a pair of wings, two antennae, two black eyes, and a pair of long teeth. Similar to fleas, they caused great amounts of itchiness by biting furry creatures such as the sentient Ewoks of Endor, causing those infested to scratch themselves.
