Control groups that returned to their ancestral homes tended to do well, and those that were transplanted into a new environment generally died. The web consists of a durable silk frame made up of the outer bridge lines with internal anchor lines that are pulled downward to create spokes. As their net-like webs wait for prey to be caught, long lines of sticky silk are connected to the ground. Orb weavers often redo their webs daily and have a memory for spaces theyve used before. The abdomen is subrectangular, with somewhat flat sides, and has small tubercules at the front. KELLY: In this way, the spiders can snag their prey at ground level and then slowly hoist them into the air, adding band after band of silk, which creates the necessary tension to lift the animal closer and closer.

The most interesting results came from colonies made up of spiders that had been forced into a composition different from the one they grew up in warrior-majority colonies containing spiders from mostly docile groups, for example. This family has more than 100 genera, most of which are harmless. Additionally, some orb webs have extra flourishes zig zags, spirals and bands made up of bright white non-capture silk, detritus or even egg sacs.
