Collembola are tiny, wingless insects which jump by means of a forked tail-like appendage that folds under the body. Mouthparts are formed for chewing. Bodies are elongate or globular, usually white, but some are yellowish brown or gray.

Springtails are common in moist locations, in leaf litter and under loose bark. Some species are important pests in greenhouses and mushroom cellars. Springtails are abundant at the soil surface, but are easily overlooked.

Metamorphosis is minimal (young resemble adults except for size). They are microscopic to 1/4 inch long.
