nemapogon cloacella, the cork moth, feeds on fungi. i caught this one flying around an old woodpile; it also comes to light-traps. the previous evening, i put my trap among alders and caught twocarpatolechia proximella, which feeds on alder and birch. there are some similarish species, not all included in sterling et al.'s field guide, but a well-marked individual like this one is distinctive.
