Hello Sean, The moth is certainly a Dioryctria but I'm not sure I'd want to go further from that picture. It needs a really clear image of the outer zig-zag cross-line, preferably taken from the opposite side to this image because of the way it has folded its wings, as well as an accurate wing measurement. Knowing the wing length should hopefully cut down the possibilities from four to two (there is a little bit of overlap but abietella and sylvestrella are generally the largest) but even then it might not be possible as this is quite a difficult little family - and only males can be determined by dissection.
