These are good-looking bugs, albeit tiny ones. I'd say five or ten of them could fit on a quarter. Like so many insects, Eastern babias are easily passed by, due to their diminutive stature, but if noticed and inspected turn out to be veritable objets d' art. Glossy black and shiny as fresh paint, the beetles are emblazoned with a brilliant scarlet shoulder epaulet.
So, I have learned two things about babias. They are responsible for some of the caterpillar-like grooves eaten from leaves, and the women treat their men rather shabbily.
As far as other natural history tidbits regarding this quite showy and interesting little bug, well, there doesn't seem to be much information out there.
The wacky world of insects is always full of surprises.
