Long Bodied Cellar Spider

These spiders can't seem to take a step without leaving a trail of webs. I watched a carpenter ant struggling but thought maybe it had been poisoned. Then I realized that there probably was a nearly invisible trace of Pholcus web it was stuck in, when like a lighting bolt one of these shot out at it from behind the microwave and started it's web toss. I have observed this spiders just ambling across the floor, although their long legs help them cover a lot of ground, they just take their dear sweet time and when watching them build webs, you would think they were the hapless clods of nature, but that behavior is so misleading. The festooning of webs wherever they travel I guess is meant to trap anything that comes in contact with them. I heard some older gentleman refer the them as carpenter spiders because of this habit. At the end of the summer I cleaned up a web where a large Pholcus was busy catching ants. I left him there ridding me of the dreaded carpenter ant who drops from the trees over-hanging my house. When ant season passed, he moved on and when I took the broom I was rather amazed at how strong the webs are, but not sticky like you mentioned. They are the masters of the game, and quite engaging little fellows, and catch all the spiders which frighten me.
