Reverse positional orientation in a neotropical orb-web spider, Verrucosa arenata

摘要: Most orb-web spiders face downwards in the web. A downward orientation has been proposed to be optimal strategy because run faster and thus can catch prey quicker. Consequently, also extend their web lower part, leading top-down asymmetry. Since majority of downwards, it difficult test effect on capture In this study, we explored influence reverse foraging efficiency asymmetry Verrucosa arenata, a neotropical spider that faces upwards We show does not imply species. V. arenata captured more part but per area upper part. The average running speeds did differ between upward running, heavier took longer while upwards. discuss these findings context
