"Hymenoptera" means "Membrane-wing".

Bees have two pairs of membranous wings. This section includes those families that are most commonly identified as bees, although technically it is more complex and the line between bee and wasp is no longer viewed as a true scientific distinction.

"Bees are alright when alive you see,
But when bees die you really should see 'em
Pinned on a card in a mucky museum."
~From the Bee Song
