1.  Resident Status - BR = Breeding resident; TC - Frequent to common temporary colonist; RC - Rare temporary colonist; FS - Frequent stray; RS - Rare Stray; 

2.  Conservation Status - EXT - Extirpated; E - State Endangered; T - State Threatened; SC - State Special Concern

3.  Most Celastrina in Maine in flight during May and June are the Cherry Gall Azure. These include central and northern populations with a high proportion of individuals exhibiting the "lucia" or "marginata" phenotypes on the underside of the wings.  These populations have sometimes been referred to as Celastrina lucia Kirby, but are conspecific with C. serotina. There is also a phenotypically similar taxon that may an undescribed sibling species that occurs in black spruce bogs in central and northern Maine

4.  This undescribed taxon was recently found in extreme southwestern Maine and emerges before the Cherry Gall Azure in southern New England, often as early as late March in years with early springs.  Males are distinguished from other Celastrina in Maine by the presence of elongate androconial scales that cover the entire upper surface of the wings.  These scales cover only the wing veins in other Celastrina species in Maine. This species uses highbush blueberry as a host and adults typically exhibit a well developed "lucia" or "marginata" phenotype on the underside of the wings.

5.  Plebejus melissa samuelis (Karner Blue) is the only federally endangered butterfly in Maine; It is now extirpated.

6.  Two poorly differentiated subspecies occur in Maine; myrina (Cramer) in the southwest, and atrocostalis (Huard) in the north.  A broad blend zone occurs across central Maine.  

7.  The northern limit of the blend zone between the subspecies L.a. astyanax (Fabricius) (Red Spotted Purple) and L. arthemis occurs in southwestern Maine where some individuals may show reduced white banding on the wings and rare individuals may closely resemble the Red Spotted Purple phenotype.

8.  In southwestern Maine is subspecies alope (Fabricius), which has a well-developed yellowish to orange patch on the forewing. In northern Maine is subspecies nephele (Kirby), which lacks the forewing patch.   A broad blend zone occurs between these two subspecies in southern and coastal Maine as far east as Calais producing phenotypes of intermediate appearance.
