Green Hairstreak Callophrys rubi
The most widely distributed of the four hairstreak species n the county, using a wide variety of larval foodplants, Green Hairstreaks are very easy to overlook with rather drab brown upperwings and are very well camouflaged when at rest with wings closed. Even so, freshly-emerged adults in May have a beautiful green underwings and are well worth seeing.
