* Phylogenetic sequence #154050.
Four Samea species are found in America north of Mexico.
Wingspan of female about 20 mm with the males noticeably smaller.
Adult: forewing grayish-brown with three groups of several white spots in AM, median, and PM areas; male has larger spots than female, and/or less extensive brown areas between spots, due to smaller wing; middle of fringe has dark gray shading and larger dark marks than along remainder of fringe; hindwing in male has large white patches covering most of basal two-thirds, with thin dark median line and row of three white spots near outer margin; hindwing in female is similar except for thick dark median line and two rows of white spots near outer margin

male/female compared note the costal margin

specimen identified by DNA analysis (BOLD) from Mark Dreiling
North Carolina to Florida, west to Texas, and south in the neotropics to Brazil.
Adults fly most of the year in the far south.
Type locality: Brazil. Colombia. French Guiana, Cayenne

* Samea multiplicalis is very similar but the forewing fringe lacks the wide dark shading near middle, and has dark marks along fringe that are approximately equal in size.
Moth Photographers Group has illustration for distinguishing the two species.
