This was a package installed about 10 days ago, I do agree that this picture looks like she almost doesn't have wings. I did not notice her wings being strange when we installed and did not when we saw her on the comb in that picture. She's laying like a champ, though, at the moment. I did not notice the "varroa" when we saw her the other day either. I have pretty good eyes and saw a few mites just when dumping in the few packages I've installed.DWV is just that, a Virus. Varroa carry the virus by nature. I'm not saying for sure that she has it, but her wings look very strange in the photo, and to me it looks like DWV. It also could be that she fought with another virgin prior to winning the hive, etc and they got chewed on or something. In any case, if at all possible i would remove that varroa from her and get rid of it.
I thought this as well, just looked like it would be almost impossible for the angle to make that "part" appear where it does in the picture. She almost has to have had her head looking down into that cell, which may explain why her wings look strange too.It's not a mite, it's just the base of her thorax and she's cordovan from the looks of it which is why her thorax is more brown than black in color. Take a look at this picture, you can see the 'mite' shaped structure at the end of the thorax, that is all and the angle of the picture.
