I think this is one of the Grass Miner Moths but can't seem to find a good match here. Any ideas?

-EDIT-

Started thinking about where I found this moth. It wasn't on grass and it seemed to be feeding on the leaf...

Just found Leaf Blotch Miner Moth family but still can't find a match there.

Leaf blotch miner moth
This moth is a tiny gracillariid called Porphyrosela desmodiella; it is the only described North American species in this genus. The larva makes a tentiform leaf mine on the underside of the leaflet of a number of different species of legumes (i.e., plants in the family Fabaceae), including Lespedeza capitata and Desmodium spp. (after which the moth is named).

With moths, the larval association of each species with its host plant is specific; that is, the larva of a given moth species is able to survive by feeding on only one plant species (or perhaps a few related plant spp.). Adult moths, on the other hand, are very mobile, flying about from here to there in search of nectar (from no particular species of flower) and mates. Therefore, the plant species on which an adult moth might happen to be observed/photographed at any time is random and is most likely not its larval host plant.

 
Thanks all!
