Family: Yponomeutidae Checklist Number: 16.002
Yponomeuta padella Linnaeus, 1758
Orchard Ermine
There are just two July records of this species which is probably a wind-blown wanderer rather than resident on the Outer Hebrides. Similar to others in the family but slightly smaller, it has a greyer background colour and different arrangement of spots. Larvae feed gregariously in a web on Prunus species and hawthorn (Crataegus)
