Hellinsia ares is a moth of the Pterophoridae family that is endemic to Utah. The wingspan is 20–22.5 millimetres (0.79–0.89 in). The head is brown, but tawny-white between the antennae. The antennae have a row of variably heavy brown dots above. The thorax and abdomen are tawny, the latter with some single dorsal brown dots in the posterior margins of the segments, but otherwise immaculate. The forewings are even ochreous-tawny. There is a brown dot near the middle and cleft of the cell preceded by a heavy but not large brown spot, from which a few scales sometimes extend to embrace the extreme base of the cleft. There are a few scattered brown scales on the wing, mostly along the inner margin near the base. The fringes are greyish tawny with a dark brownish grey patch preceding the apex
