Poanes aaroni
(Skinner, 1890)
Aaron's Skipper, Saffron Skipper
Poanes aaroni, commonly known as Aaron's Skipper or the Saffron Skipper, is a North American restricted to salt marshes along the Atlantic coast. The exhibits vivid orange coloration with broad black wing borders. It has a highly specialized ecological relationship, with larvae feeding exclusively on smooth cordgrass (Spartina alterniflora). Four are currently recognized, reflecting geographic variation across its limited coastal range.

Identification
Distinguished from other Poanes and coastal skippers by the combination of vivid orange upperside with broad black borders and the pale stripe on the hindwing underside. The salt marsh and Atlantic coastal distribution further separate it from similar orange skippers. identification requires examination of subtle wing pattern and size differences.

Appearance
Upperside of wings vivid orange with broad black borders. Underside of hindwing paler orange with a pallid stripe in the center. Overall coloration distinctive among coastal skippers.
Habitat
Salt marshes along the Atlantic coast. Strictly associated with coastal wetland environments where the larval plant grows.
Distribution
Atlantic coast of North America, restricted to salt marsh . occur in different portions of this range: P. a. aaroni (Aaron's skipper), P. a. bordeloni (Bordelon's skipper), P. a. howardi (Howard's skipper), and P. a. minimus (swamp skipper).
Diet
Larva feeds exclusively on smooth cordgrass (Spartina alterniflora). food sources not documented in available sources.
Host Associations
- Spartina alterniflora - larval exclusive; smooth cordgrass
Ecological Role
Specialized herbivore in Atlantic coastal salt marsh . Dependent relationship with smooth cordgrass suggests potential role in energy transfer within marsh , though specific ecological impacts not documented.
Similar Taxa

- Other orange skippers (Hesperiidae)Similar coloration but differ in preference and wing pattern details; coastal salt marsh association is diagnostic for P. aaroni

Subspecies
Four recognized: P. a. aaroni Skinner, 1890 (Aaron's skipper), P. a. bordeloni (Bordelon's skipper), P. a. howardi (Howard's skipper), and P. a. minimus (swamp skipper). Subspecies reflect geographic partitioning along the Atlantic coast.
Taxonomic history
Originally described as Pamphila aaroni by Skinner in 1890, later transferred to Poanes.
