furcula
Quick Summary
The furcula is a forked appendage found on the abdomen of springtails, a group of small, primitive, wingless insects. This appendage is held under tension by a clasplike structure called a tenaculum. When released, the furcula acts as a jumping apparatus, allowing the springtail to catapult itself, though their primary mode of movement is crawling. Springtails are found globally in soil and leaf litter and feed on decaying matter.12

apterygoteLocomotionCollembolans have a furcula, a ventral abdominal springing organ that enables them to spring rapidly into the air. Apparently, Zygentoma and Archaeognatha have developed the median tail filament (telson) to assist in supporting the abdomen during movement. Archaeognathans can also spring with considerable agility by using the body…
