Not unusual for a spider to rebuild its web daily/nightly. Some just do repairs, others completely rebuild the web. If you want an idea of where your little web builder might be, one common spider trait is to sit at the end of one of the web threads, where it can keep one "foot" touching a web in order to sense any vibrations from trapped prey. The end of the leg has specialized hair just for this purpose. They're very good at telling the difference between vibrations from wind or the movement of a branch, and those of a trapped "meal." See if one of the anchoring threads leads to a likely hiding place. You may need to check it at night; early mornings; or evenings when a lot of spiders are active.
One trick to sometimes spotting them at night is to hold the flashlight up alongside your temple while shining it at suspected places from a distance so as to not frighten the spider into diving deeper into its hiding place. Believe it or not, light can be reflected from the spider's eyes back at your eye, and this glint is easier to spot than a well camouflaged spider. The trick works great for lots of night critters, including moths and other larger critters crunching around in the shrubs.
Happy hunting. Oh, and FWIW, I will usually try, if possible, to relocate rather than kill outdoor spiders. They're predator species that tend to like to eat more annoying bugs such as flies, mosquitos, roaches, etc. In other words, they're "good bugs, who eat bad bugs." Any enemy of my enemy... well, you get the idea. And hey, a spider that lives on your Spyder??? Kinda sounds appropriate somehow. :ani29: :spyder2:
