City spiders may spin low-vibe webs
Anchoring silk on human-made structures might change background vibrations and make prey detection harder

Spiders that spin webs on concrete and steel structures may be missing some good vibrations — and have a harder time catching their next meal.
Attaching silk strands to walls, metal poles and other human-made materials can dampen the usual background vibrations in spider webs, says Chung-Huey Wu of National Taiwan University in Taipei City. In lab tests, spiders in vibrationally quiet webs were not as quick as spiders in livelier webs to detect prey, Wu and Damian Elias of the University of C...
