Purple Hairstreak

Neozephrus quercusPhotoPhoto By Barry Watts

Wingspan    Male 33 -40mm    Female 31 - 38mm 

Description Our largest hairstreak and one of the most abundant, it can be elusive as it spends most of its time in the canopy of oak trees. At a distance the butterfly looks either grey if resting with wings closed (underwings) or dark if basking and you see the upperwings. These fast-flying butterflies look silvery against the canopy.
