Dung beetles are used in Thailand as a "wholesome additive to curries." In addition, as grubs they are pretty big with limited chemical defenses.

Dung beetles are members of the subfamily of scarab beetles. They shape manure into a ball (sometimes as large as an apple) with their strong antennae similar to fingers and their forelimbs. Dung beetles are equiped with strong hindlegs to roll their dung balls.

Thus, dung beetles are a valuable resource for animal waste removal. They've been imported into areas such as Australia in order to reduce the amount of cow manure. Importation was necessary because native dung beetles were not accustomed to moving cow manure.
