6422. I bought a air conditioner at Costco. While opening the box, this spider jumped onto my head. The air conditioner is made in China but packed in Ontario. Can you tell me if this is a Canadian spider and harmless. I released him outside before considering the matter. Montebello, Quebec. Canada
Number 6422. This is a female dark fishing spider, Dolomedes tenebrosus (family Pisauridae), the largest spider species native to Ontario. Not at all dangerous to humans, and in spite of its name, these can be found a long distance from water. Click here for more detailed information.
