Ballooning: data from spiders in freefall indicate the importance of posture

, : Ballooning: data from spiders in freefall indicate the importance of posture. Journal of Arachnology, 202: 107-113

Ballooning, the aerial displacement of a spider caused by friction between air and the spider and silk, was studied, using stroboscopic measurement of the rates of fall of spiders slowed by known lengths of silk and direct measurement of the drag generated by moving air at the surface of spiders in various postures. The terminal velocities of spiders trailing silk, derived from their rates of fall at known distances from release, were very variable.
