On the glass in the porch. Quite stunning but have no idea what it is. About 1" long - white with black/dark spots.
No interactions present.
While this looks like an Yponomeuta, if it is 1" long it's probably too big? Thistle Ermine perhaps?
Thistle Ermine has a completely different pattern of black dots, without the long rows running the length of the wing as can be seen here. The general feel of the shape of this moth is also more Yponomeuta rather than Myelois.
