Identification
The genus is distinctive among American Plume Moths (Pterophoridae) in having both fore-wings and hind-wings entire (i.e. lacking the irregularly-cleft "fringes" along the trailing edges of the wings, typical of other plume moths). In living specimens, the posture enables easy recognition in combination with the specialized habitat. Wings are angled upward forming an overall "Y" shape, rather than at right angles to the thorax forming a "T" as in most other Pterophorid genera:
   
Range
Southern California (including Channel Islands) and both coasts of Baja California, Mexico.(1)
Habitat
Coastal salt marshes.(1)
Season
Larvae have been found in March (emerging in April) and May (emerging in June). Adults have been collected from March to May and also from September to October, suggesting at least two generations a year.(1)
Food
Larval host plant is the salt marsh plant Alkali Heath (Frankenia salina).(1)
