It is difficult to see. I know from experience that it is difficult to photograph a spider that’s near a ceiling. It looks like a Long-legged Sac Spider in genus Chieracanthium. They make silk resting sacks, like sleeping bags. The sacs are white and usually in the wall-wall or wall-ceiling junctures. They can be clear, yellow, green, or brown.
There are some Recluse spiders that were found in Ann Arbor that weren’t identified to species level. I used Bugguide.net data. they have about 18 years of photo submissions. SpiderID.com doesn’t have any Recluse photos for Michigan.
