Jumping in springtails: mechanism and dynamics

Notes that apply across the site

• In Tomocerus longicornis and Dicyrtoma ornata the jumping organ works as a click mechanism that deforms the abdominal sclerites. The springing organ is thought to evert by blood pressure and rising tension in those sclerites, and body shape and tail length change the direction, height, range and spin of a jump. (at Abstract)
