White matter attached to backside - Popillia japonica

White matter attached to backside - Popillia japonica
Carlisle, Middlesex County, Massachusetts, USA
July 15, 2019
Size: 1/2”
Found two of these beetles and both had these strange white ‘fluff’ stuck to the back side.

Moved from ID Request.

Popilia japonica
The white fluff is just white tufts of fur that characterize this species

 
White ‘fluff’
Does this type of beetle always have these tufts? I’ve seen similar beetles without the ‘fluff’ does that mean it’s a different species?

 
Great Picture!
Yes, there are a few other beetles in the same family that are quite similar in appearance. These other beetles all lack the 'fluff'. By the way, would you consider moving this image out of ID request? The species ID of Popillia japonica is quite correct.
