Status
Edwards' Hairstreak (Satyrium edwardsii) populations are in decline, and this species is considered endangered and vulnerable in Maryland. There are now fewer than five populations known in the state, and consequently, this species has been assigned a ranking of S1 (highly-state-rare) by the Maryland Heritage Program. Edwards' Hairstreaks prefer dry rocky barrens with an abundance of Bear Oak. Loss of suitable habitat is one of the main reasons for this species decline.
Relationships
The preferred host plant for Edwards' Hairstreak is Bear Oak (Quercus ilicifolia). In some parts of the range, it may also use Black Oak (Quercus velutina) or Blackjack Oak (Quercus marilandica) (Allen 1997).
