All spiderwebs represent remarkable engineering feats, but few match the eco-friendly design showcased by some orb-weaver spiders. Take for instance the species Cyclosa ginnaga, which decorates its webs with whatever debris it can find, such as leaves and twigs. Though the ultimate purpose of the decoration is rather sinister (for luring in prey, or for concealing the webbing), this spider's eco-cred is still worth noting.
Many orb-weaver spiders rebuild their nests every day, so they are always busy recycling. This helps keep both their webs and their surrounding environment clean!
