Does your insect have a collophore?
A collophore is a tube-like structure found in about the center of the insect on its ventral (belly) side. Insects with a collophore typically have a furcula, which is a forked jumping device. When alive, the insect holds the furcula against its ventral side (underside) with a tiny latch (called a tenaculum). When the latch releases, the furcula springs downward, propelling the insect into the air. Note: Insects that possess a collophore are small (0.2-10 mm in length), so you may have to use a hand lens or dissecting microscope to see the collophore. The furcula, if present, may be easier to spot.
