This beetle is Cryptocephalus leucomelas leucomelas
, based on the pronotum and elytra markings illustrated in White(1)
. I found it mating on the leaf of an Eastern Cottonwood (Populus deltoides
) in 1977. The male (mounted on top of the subject female) was a bit smaller. I donated the male to the Dayton Museum of Natural history (now the Boonshoft Museum of Discovery
) since they only had one very old and faded specimen at the time.
