Oh,
yeah--I
do know how to conduct research!! And thanks for the compliment!
As it happens, though, last year my DIL's father found thousands of those in his yard and asked me to identify them. So when Bob asked, I was pretty sure that's what he had.
Of course, we still don't have a photo of what Bob found, and Bob hasn't reposted to tell us what his Ag agent said they are, so we have no confirmation that my guess is correct.
