Gliding Bristletail Videos

1) Jumping bristletails (Meinertellus sp.) dropped from a canopy platform in the Peruvian Amazon.  The insects were dusted with orange fingerprint powder to improve contrast.  A glass bead is dropped first to show where a free-falling object should land.  A string of flags hangs near the tree trunk to provide a reference for estimating vertical drop distances. See Yanoviak et al. 2009.

2) More Meinertellus sp. dropped following the protocol described above.  In this case, the caudal filaments were completely or partially removed before the test; their relevance to gliding is quite clear. See Yanoviak et al. 2009.
