Nightmare at porch lights
A first look at a Stag Beetle, which is a member of the Family Lucanidae, is enough to make a casual observer back off several paces. For the entomophobe, well, spotting one of the these fearsome looking insects is enough to send the viewer running away in blind terror. For me, of course, noting that a likely representative of the Yellow-thighed Stag Beetle clan has been attracted to the kitchen porch lights is certainly an event that has me sprinting for the micro-lens-equipped dSLR. Lucanus capreolus is a pretty common visitor around here, and though the males, which have the oversized mandibles, use their impressive equipment in wrestling matches with rivals, I don't think they can hurt humans. However, I, for one, have not tested that theory.
