Chris had a slight typo in the carrion beetle's name -- it should be
Necrophila americana -- AND this is the same kind of carrion beetle that Pat
and I saw on a trail at Noggins Farm in Greenwich about a month ago?  I read
in one of my books that this species specializes on carcasses that are quite
old and dried out, I believe.

I wasn't able to view the red dots on the leaf that Jeannie photographed.
What kind of trees were they?  If these dots were raised up into pimple-like
growths, they are probably galls caused by gall mites, which with a strong
hand lens do not look at all like mites -- the body in elongate with only 2
pairs of short legs near the front.

If the spots are flat and circular, they might be spangle galls caused by a
gall midge perhaps?

Cheers from Jim in Wolfville
