Femora: in insects, the third segment in the leg, the largest segment of the leg in most adult insects. In tetrapods (vertebrates with four limbs) the upper bone of the hind limb.
Nymph: stage of insect development, similar in appearance to the adult but sexually immature.
Tibia: in insects, the long (often narrow) segment of the leg that attaches to the femora or femur at the end closest to the body. In tetrapods (vertebrates with 4 limbs), the forward facing long bone in the lower hind limb (the shin bone).
