Spiders some are stalkers some are web weavers. According to folklore they are a symbol of the cosmic order. Depending on what time of day they visit it could be good or bad luck. Don't kill one inside your home it will rain. This tale I grew up hearing and it is best to let them out!
This fellow is a crab spider and he's a stalker waiting for his prey. He looks just like a crab and he'd fit right in at the sea shore. This one is brown but I have seen crab spiders that are white and yellow too.
