• Satyrium favonius ontario

  Northern Oak Hairstreak

  Satyrium favonius ontario, the Northern Oak Hairstreak, is a canopy-dwelling butterfly subspecies found in the northeastern United States. Its perceived rarity appears largely due to detection difficulties rather than actual low population numbers, as adults spend most of their time in oak canopies rather than at ground level. The subspecies has been documented feeding on non-nectar sources including oak gall exudates and honeydew. Listed as a Species of Special Concern in Massachusetts.
