>>I didn't see the article, but it sounds like a species of aphid.
According to
my "very old" Text by Comstock some species have wingless females that
reproduce parthenogeneticlly until the host become crowded then a
generation
appears that develops wings and moves to a secondary host which also
reproduce
parthenogenetically. After several generations of again wingless forms, a
winged form appears and moves back to the primary host and reproduces
sexually.
There is so much variation that it's quite confusing and as I say, I don't
have
up to date info., but the aphids sounds like a possibility.>>
Interesting about the aphids. But unless my memory is failing altogether,
it was not
aphids which were being described. I'd have recognized the word "aphids"
and whatever
these beasties were was a name I did not recognize at all.
I went through all the "piles" of "good stuff I must read someday" and did
not locate
the article. If I do...
