Welcome to the forums! I have been fortunate enough to have visited Delaware and seen many pinned specimens from there. I have seen pinned specimens(collected in DE) of Cotinis nitida, Lucanus capreolus, Dynastes tityus, Osmoderma eremicola, Xylorectes jamaicensis,and some fantastic giant divers....the D. tityus I saw was an exceptionally large male.....That's all I'm really finding were I live. Kind of wish I could find other beetles. Hopefully once it warms up a bit there will be more things to find
