Spiders Attract Dinner with UV-Reflecting Webs
Ella Davies, BBC News
Orb-weaver spiders attract insects to their webs with ultraviolet (UV) decorations, a study has found.
The function of the intricate patterns in the webs of orb-weaver spiders is subject to much debate in the scientific community.
Previous explanations have identified them as bird scarers, mating signs, sun shades and camouflage.
Researchers now suggest the UV light-reflecting patterns could trick flying insects into landing on them.
