Note that I didn’t say “busy bee” because although this creature resembles one, looks can be deceiving. This happens to be a sand wasp in the Sticitella genus.
Though relatively harmless to humans, they come by their common name, Butterfly-wolf Wasp honestly. They prey on small butterflies, stunning them before dragging them into their sandy burrows. A female can stuff as many as ten of them into her lair before laying her egg. After all her hatchling will be hungry!
