However they do not appear more closely related to one another than they do to the insects. Recent genetic studies suggest that the Collembola are a separate evolutionary line from the other Hexapoda. Members of Collembola have six or fewer abdominal segments. \nThese tiny animals are less than 6 mm in length. An abdominal tail-like appendage, called the furcula, in some species is folded beneath the body, and is used for jumping. \nSpringtails are frequently found in leaf litter and other decaying material. \nThe suborder Arthropleona has an elongated body in contrast to the more globular body of the Symphyleona.
