I was hanging out in someone’s backyard on a recent afternoon when I noticed some tiny moths flying around. One settled on a small tree, and I got a photograph.
And because the internet is wonderful, sitting right there I could search for a match on my phone. It’s Oecophora bractella, a European moth that seems to have established a population locally. It was first seen in the US in Seattle in 1998. It lives on decaying wood and fungus. That seems right; a tree was cut down in this yard a few years ago, and the logs are still there, gradually decaying.
