Selenops in Michigan?

As long as I have lived here in S.E. Michigan, I have seen what we usually call a "pine spider." They are usually found in pine trees, under bark, and in woodpiles. Sometimes in the summer, I have parked under a pine tree and found many of them crawling on my car.

They are very, very flat. The colouring can range from mottled brown or grey to yellowish, sometimes with a tinge of green. They resemble a crab spider most closely (Thomisidae), though I am SURE these are not Misumenia vatia, xysticus, or anything of the sort. The size ranges from 3 mm to about 6 mm (body).

I need to get a closer look at the eye pattern, but I believe these are actually a Selenops sp.

I've tried to research native Michigan spider species MANY times, but very little is on the internet pertaining to this search. The only Selenops photos, or any info I can find is all about Floridian or African ones!

Are Selenops sp. native to Michigan and the eastern states?

ANYWAY, I found what I suspect to be one crawling across the windshield of my car yesterday, so I picked it up and put it in my woodpile, where I had also found another similar spider a few days before.

Later that day, I noticed a flat-looking egg sac near my passenger side window. I'm pretty sure it must have belonged to the spider I saw earlier that day. I count at least 30 spherical yellow eggs inside, the size of the tip of a needle.

I have collected the sac, and HOPEFULLY, I will be able to study these spiders more closely when the spiderlings hatch-- and POSSIBLY make an ID!

Has anyone else ever found or kept these sort of spiders in the Tri-State area?

I personally would like to see this spider or a pic of it...I am in Ypsilanti...maybe we can meet up and do a hunt
Could be thanatus or philodromus which are both here

You've got me curious. I just moved to S. E. Michigan about a month ago.

Hmm..I think you may possibly be right

I think this may be a Philodromus sp., but to my eye, the spiders I've seen appear MUCH flatter than the ones I see on bugguide.net.

I looked around for the past few days for another specimen to photograph, but no such luck. :wall:

The mystery eggs seem to be coming along. I swear I can see legs developing. I wish I had a microscope or a macro lens, so I could peep them out better. :(

P.S. I found a kick-*ss Herpyllus ecclesiasticus in my bathtub this morning! Who knows how it got in here, but who CARES? I've been wanting one for a while, now. :D

The tiny yellow eggs are still coming along nicely.

They have gotten darker, and the legs are more pronounced.

I've been keeping them in a deli cup, breathing into it once a day until it appears foggy-- to keep them humid.

I can't wait to see what these hatch into!!!! {D

I don't believe it would be any of the genera of the family Selenopidae, given the locality. Most likely you hit it on the head with the Crab Spider family Philodromindae (there are some that fit the overall description you gave).
