Jumping technique and climbing behaviour of the collembolan Ceratophysella sigillata (Collembola: Hypogastruridae)
2000
Jörg ZETTEL | Ursula ZETTEL | Beatrice EGGER
Ceratophysella sigillata uses protrusible vesicles on its antennae and posterior end as sticky landing devices to avoid tumbling upon landing. This technique facilitates its orientated movement during winter migration. It allows the animal to use directional jumps without rebounding even when climbing tree trunks. The antennal vesicles are present only in the surface active morphs of C. sigillata, and only these individuals jump readily. The vesicles are everted only when the animal has time to prepare the jump. In an escape leap, they are not protruded and therefore the animal tumbles upon landing.
