  1. Resident StatusBR = Breeding resident; TC - Frequent to common temporary colonist; RC - Rare temporary colonist; FS - Frequent stray; RS - Rare Stray;  HIS - No records after 1995; EXT - Extirpated
  2. Conservation Status E - State Endangered; - State Threatened; SC - State Special Concern
  3. Bolaria selene  - 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.  
  4. Limenitis arthemis - 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.
  5. Cercyonis pegala - 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.
