April 19 2017 was sunny and mild.
Overnight, 19/20th, temperature dropped below freezing and we had 1" of new snow,
Found this 'barely-alive' bee on a dry spot on our deck.
Brought it indoors but it never recovered. Took a look under a lens and saw it was heavily infested with mites. Killed the mites with alcohol.
Top: bee after alcohol treatment
bottom: mites that washed off in the alcohol.
I have seen many mite-infested insects but don't recall ever seeing this many on one insect.
I believe the bee is a solitary, soil-dwelling Halicitid Bee.
Will clean up the poor bee and take a closer look at the mites.

I cleaned the bee as best I could.
Family: Megachilidae; Osmia sp. (Mason Bee).
The mites were 6-legged nymphs and as such not structurally interesting.

I have seen mites on insects that have been very firmly attached. These mites were not attached, except to the hairs and each other, and appear to be phoretic.
