Taxonomy
Superfamily: Zygaenoidea Family: LimacodidaeP3 Number: 660047.00 MONA Number: 4691.00
Comments: One of two representatives of this genus currently recognized in N.A. Both occur in the east, though only semifascia has been confirmed in NC.
Identification
Field Guide Descriptions: Covell (2005)Online Photographs: MPG, BugGuide, BAMONATechnical Description, Immature Stages: Wagner (2005)                                                                                 
Adult Markings: Entirely warm brown or reddish brown. The FW bears a single, wavy line that run halfway across the FW from the midpoint of the inner margin. This line, typically silvery white to yellowish white in color, varies in appearance from relatively wide and obvious to very thin or barely discernible. Larvae: Salmon, pink, or most commonly bright red with dorsal and lateral areas each with set of three thin blue-black stripes. Fascicles of 20 or more short, whitish, stinging spines grouped in four lines that run the length of the body. Anterior end bears four dark, "gumdrop-shaped" conical projections of equal size (Wagner, 2005).
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.

Habitats and Life History
Habitats: Most of our records come from dry woodlands and flatwoods. However, we also have at least a few from wet savannas and peatlands.
Larval Host Plants: Polyphagous, feeding upon cherry, oak, pecan, persimmon, and presumably many other woody plants (Wagner, 2005).
Observation Methods: Readily attracted to lights.

Status in North Carolina
Natural Heritage Program Status:
Natural Heritage Program Ranks:
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands.
Comments: The vast majority of records are from the Coastal Plain, with a few records from the Piedmont and fewer still from the Low Mountains. Given that the reported food plants are widespread, other habitat factors, such as xeric conditions, are likely to be important factors in controlling the distribution of this species in the state.
