27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Hello all,

Here is a specimen found near my house (near Vermont). Would it be possible to identify the genus and the species? I'm suspecting Hellinsia sp.

Thanks for helping me :)

It certainly appears to be a Hellinsia sp. Here's a website that should help you get a species. http://mothphotographersgroup.msstate.edu/slow.php?plate=15&page=2&sort=h
