SpiderHere's an interesting BBC article about research on spider survival strategies.

Researchers hypothesized that a species of spider that decorates it's web with prey carcasses would benefit from a camouflage effect, but it turned out that these spiders actually received many more attacks from predators than those with undecorated webs. For these arachnids, unless the web decoration serves another purpose I imagine the trick worked for a good while before the predator-prey arms race escalated to the next level. Now that the other side seems to have the upper hand, I wonder for how long the spiders will continue to direct their energies pursuing a futile strategy. Other spiders are stepping up their game, for when the researchers tested the idea on another species of spider that decorates it's web with actual size replicas of itself, they found that that the decoy effect outweighed the increased risk of detection.
