The house where I live is ready for Halloween thanks to the generous numbers of spiders living around it. By the front steps, there’s a small Hawaiian Garden Spider and several crab spiders.

One day, I came home and saw a wasp flying close to the various webs. I thought it was dicing with danger, but soon saw that wasn’t the case. Instead, it would approach a web and bob its head toward the spider. It didn’t seem to be a terribly threatening act, though perhaps it was from the spiders perspective. The wasp didn’t push home an attack, but would instead fly away, settle for a bit, and preen itself.

The garden spider didn’t seemed to be bothered by the attention, but the crab spiders would drop suddenly on a strand of silk, before returning to their web as soon as the wasp moved on. I watched these maneuvers for five or ten minutes before heading inside. No webs were damaged, no spiders hurt, and I still don’t know what was really going on!
