Walnut husk fly
Rhagoletis completa
The walnut husk fly is about the size of a housefly and very colorful. It has a yellow spot just below the areas where the wings are attached and iridescent, greenish eyes. The wings have three prominent dark bands, one of which extends around the wing to form a V-shape (Figure 1). The banded wings distinguish it from other flies found in the walnut orchard.
