Notes. Found frequently in wooded areas in northern Portugal, this species has clearly been previously overlooked, perhaps due to its association with broadleaf woodland where it is known to forage extensively from woody plants such as Acer , Rubus , Crataegus , Quercus , Rhamnus , Frangula and Ilex ( Wood and Roberts 2017) . In Portugal, this habitat type is found only in the north of the country.
