|Morning glory plume moth, Emmelina monodactyla|
I have found these around here before, and had tentatively identified them as the Morning glory* moth. Tonight, looking again at the samples on BugGuide, I found a helpful annotated photo, which more or less confirms the id.
The markings pointed out on the photo are:
- the curved wing tips. Check.
- Three dots along the centre back of the abdomen. Check.
- A dot near the centre of the wing. I think I see them, although I'm looking at it from below, so I'm not really sure.
Next time, I'll know what to look for.
The caterpillars of these moths feed on Convovulvus species, including our pestiferous bindweed. But one of my neighbours planted Morning glories last summer: I'll check her plants for the caterpillars later on.
