As kids we used to see a green insect we called June bugs, but web
research shows that June bugs are brown. So what are these guys?
Thanx.

June beetles can also be green. From the a UKY web page:
Green June beetle populations are cyclical and populations were high
for several years about ten years ago. So I expect that we are likely
to fight these battles for a few years before the numbers decline.
