Common all over the State, but less so than the next species, which it 

 closely resembles. Found in the vicinity of streams, and during July and 

 August frequents, by hundreds, the flowers of peppermint, Mentha 

 piperita, and allied species. Food plants, asters, wild sunflowers and 

 Actinomeris. The larvae pass the winter, when partly grown, beneath the 

 shelter of objects on the ground, and the imago has been taken in West- 

 ern Indiana as early as May 17.

 The two forms of this species, marcia, Ewd., and morpheus, Fab., are 

 both very abundant, especially the latter. Three or four broods are 

 produced each season, the first one (marcia) from hibernating larvae, ap- 

 pearing about the tenth of May, and the others at intervals of six or 

 eight weeks thereafter. In company with Colias philodwe, they flock 

 about muddy places in the roads and the damp, sandy margins of 

 streams. .Food plant, asters.
