The one in the photo actually covered an entire sarr pitcher mouth with its nest web. They do catch bugs attracted to the pitchers, thieves! I like them though and probably spend way too much time watching the spiders who make the bog their home, especially the jumping spiders.
All sizes of jumping spiders come into the house at times riding on the dogs, but I leave the removal of those to someone else using a cup and piece of paper as I have a bit of a phobia to spiders in the house, haha. I will not allow them to be killed though, they go back outside away from the house, usually to the bog. I have been bitten by spiders before but never a jumping spider, by the looks of the mouth parts on the big ones I imagine it can be a pretty nasty bite.
