Tiny - Elachista madarella

Size: ~3.5mm
Found another one of these tiny critters. Assuming it's a moth. Took a couple more pictures but don't know if they're any better than the one we posted the other day.
Getting a nice collection of these in the guide Robirdman's and Tom's even though we don't know what it is!

Tiny moths
The moths in these images are Elachista sp. (Elachistidae). The commonest of the metallic-banded Elachista species in Illinois is E. madarella, the larva of which is a leaf miner on sedges of the genus Carex. There are a few other metallic-banded Elachista species in Illinois, but they are not nearly so noticeably common as is E. madarella; so, that very probably is the identity of the moths in these photos. The earlier suggestion of Nepticulidae has to be ruled out, by the way, because the moths in your photos clearly have smooth, shiny-metallic, slicked-down scaling on the head. In Nepticulidae, the head bears a very prominent tuft of upright, hairlike scales that renders the appearance of the head fuzzy or shaggy, rather than smooth and shiny.

 
Terry, what do you think
about the Tom's image which I included in a thumbnail? Just click on it and leave a comment there. And can you click on your name and tell us more about yourself?

I showed these pictures to so
I showed these pictures to someone who rears leaf miners, and he said they were Nepticulidae (at least the main pic). They are nearly impossible to identify without knowing the host plants or mining habits. Besides that, many are undescribed. I've tagged this under the family until over-ruled.
