Beth has blond hair that reach down past her shoulders, and paler skin than the rest of her family. Like all wasps, she has two antennas protruding from her forhead, yellowy eyes, two mandibles growing out of her chins and two from her mouth, and a long extendable tongue.

Her upper arms have bumps near her shoulders and end in three-fingered hands. The rest of her body is identical to that of a wasp. She wears pink lipstick and some form of mascara.
