How long can wolf spiders live?

by Eric Neubauer

Sometimes people ask me how long wolf spiders live, and that’s a question I have too. I’ve been looking and lately spotlighting for spiders on my property for a while, and suddenly I can’t find any Schizocosa avida day or night. I know another observer on iNat about 150 miles to the northwest who hasn’t seen any recently either.

Checking the months of my observations, I find a peak in March and few from August to December. They have to be there, but are probably too small to be noticed. So, I have one answer: they live about 14 months and are mature for the last few.

Observations for their entire range on iNat show a similar pattern. On the other hand, adults of some Pardosa are present and breeding year round, so figuring out how long they live is a lot harder and could be less than a year. I suspect Hogna antelucana live well into their second year at least. So, it’s complicated.
