Hypena decorata


Family: Eribidae Hypena decorata August 20, 2019 San Juan Island, WA

I found this on the kitchen floor the other morning (August 20, 2019). It looked like a piece of tree bark had been tracked in. When I reached down to pick it up, I realized it was some sort of moth and one I’d not seen before.

After taking photos of it (it was expired when I found it), I thumbed through my reference books, trying to see if I could identify it. After about an hour of skimming literature and photos, I finally grew frustrated and emailed Merrill Peterson at Western WA University to see if he’d seen it before.

That afternoon, I did indeed hear back from Merrill. He’s fantastic about responding and said he had to reach out to someone he knew, but finally got an answer for me.

Here’s what Merrill said, “It’s a strange Hypena decorata, like this one. I had to get some help to figure it out!” I was glad Merrill helped solve the mystery and now I can share what I found out about this moth.

Hypena decorata is in the family Eribidae, within the superfamily  Noctuoidea, the (Owlet Moths and kin). Hypena is Greek for “beard.” When you look at the fuzzy, long labial palms that project to form the moth’s snout, it does indeed look a bit like a beard.

According to the Bugguide reference, Lafontaine & Schmidt (2010) list 29 species of the genus Hypena in America north of Mexico. The moth is relatively rare to uncommon West of the Cascades, but found in southwestern British Columbia and western Oregon and Washington. Distribution records also show the species ranges to Southern California. Larvae are food plant specialists, feeding on nettles  (Urtica spp.).
