Mottled Umber (Erannis defoliaria)

Observation - Mottled Umber (Erannis defoliaria) - UK and Ireland. Description: Everything seems right for Mottled Umber except for the time of year. Came to actinic light. 4mm grid. Edit: When released the moth settled for a day or two on the outside of a window allowing this shot of its underside. Does it help with identification?
