Egg sack carrying yellow spider – Manitoba
August 31, 2009
Hello. The enclosed photos are of a lovely spider we encountered on our walk on the boardwalk over Ominik Marsh, in Clear Lake, Manitoba.
It was about 1 inch long, yellowy, and as you can see it was carrying an egg sack (we think), and had either some sort of parasite or baby spiders on it as well – the red things.
Hope you can help with the ID. Thank you for your time, and congrats on the book.
M.M.

Wolf Spider with Eggsac and Mites

Wolf Spider with Eggsac and Mites

Dear M.M.,
This is a female Wolf Spider and she is carrying her eggsac.  Additionally, she is transporting some red mites on her body.  There are some Mites that are phoretic, and use larger arthropods for transportation purposes only, but we suspect your photo shows Mites in the genus Leptus and that genus is parasitic based on some BugGuide images.  We of course would welcome an expert opinion on this matter.
