Yponomeuta malinellus, the apple ermine, is a moth of the family Yponomeutidae.

[1] The forewings are white and have 12 to 16 black dots, which are arranged in three irregular lines.

It can defoliate apple trees and negatively impact fruit production for several years following an outbreak.

[1] Y. malinellus larvae initially burrow into Malus leaves, and produce a silken web in May and early June, within which they feed.

The moth is found across England, whereas there are few reports of it in Scotland, Wales or Ireland.
