Wasps have smooth, non-barbed stingers. Therefore, a wasp is able to withdraw the stinger from the skin and continue to sting. A wasp sting does not result in a stinger being left behind in the skin. Each sting injects venom into the skin that can create a variety of symptoms on the skin and in the rest of the body.
The two kingdoms of Upper and Lower Egypt were united c. 3000 BC, but each maintained its own regalia: the hedjet or White Crown for Upper Egypt and the deshret or Red Crown for Lower Egypt. Thus, the pharaohs were known as the rulers of the Two Lands, and wore the pschent, a double crown, each half representing sovereignty of one of the kingdoms. Ancient Egyptian tradition credited Menes, now believed to be the same as Narmer, as the king who united Upper and Lower Egypt.
