I'm pretty sure this is a virgin queen. She may have drowned in heavy rain yesterday. A worker was dragging her away from the hive and I happened to catch it.
I couldn't find a milky, round spermatheca inside so it must have been clear (i.e., unmated). She is so translucent and golden! All the queen bees I have seen on the internet are leathery looking.
Her stinger is extruded. Does that mean anything? Did she die in battle?
