Isodontia auripes, the brown-legged grass-carrier, is a species of thread-waisted wasp in the family Sphecidae.

[1][2][3][4] The wasp will opportunistically use old nests made by Xylocopa virginica or mining bees.

Larvae eat for three days and then spend two forming pupae.

Oecanthus is a common prey item throughout I. auripes' range.

[5] I. auripes lives along the east coast of the United States.
