Grammia parthenice (Kirby, 1837) - Parthenice Tiger Moth


Taxonomy
Superfamily: Noctuoidea Family: ErebidaeSubfamily: ArctiinaeTribe: ArctiiniP3 Number: 930246.00 MONA Number: 8196.00
Comments: One of 36 species in this genus that occur in North America (Schmidt, 2009), nine of which have been recorded in North Carolina. The form occurring in North Carolina has long been considered to represent subspecies intermedia, which is much larger than the nominate subspecies occurring in the northern plains and boreal areas. However, Schmidt (2009) stated that more work would be needed to see if Southeastern populations are actually the same as those from Texas, where intermedia was originally described.
Identification
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Photographs: MPG, BugGuide, BAMONATechnical Description, Adults: Forbes (1960); Schmidt (2009)Technical Description, Immature Stages: Forbes (1960)                                                                                 
Adult Markings: A boldly marked Tiger Moth, second in size only to G. virgo among our species. Easily recognizable from a good quality photograph where both the hindwings and forewings are in view. The hindwings are usually red or pink (rarely yellow) and have a row of black spots located along the outer margin but lacks the ante-medial spots characteristic of virgo. The forewings are black with both narrow yellow lines along the veins and a set of broader yellow bands running longitudinally and transversely. This pattern is similar to that of G. virgo and anna but the post-median (terminology following Schmidt, 2009) is strongly bent at the midpoint in those species but is only slightly bent, if at all, in parthenice.
Adult ID Requirements: Identifiable from photos showing hindwings, abdomen, or other specialized views [e.g., frons, palps, antennae, undersides].
Immatures and Development: Forbes (1960) describes the larvae as wholly black or with some brown hair or a pale dorsal line. Grammia larvae are generally similar to one another (Wagner, 2005) and should be reared in order to determine their identity.
Larvae ID Requirements: Identifiable only through rearing to adulthood.
Distribution in North Carolina
Distribution: Probably occurs statewide except possibly on the Outer Banks and other barrier islands
County Map: Clicking on a county returns the records for the species in that county.
Flight Dates:
 High Mountains (HM) ≥ 4,000 ft.
 Low Mountains (LM) < 4,000 ft.
 Piedmont (Pd)
 Coastal Plain (CP)

Flight Comments: Has one primary flight in September but with at least one specimen collected in May in the Coastal Plain. Overlaps but is usually later than Grammia virgo.
Habitats and Life History
Habitats: Schmidt (2009) states that parthenice is one of the most widespread species in this genus and occupies a wide range of habitats, from "rich deciduous forests to the grasslands of the Great Plains, preferring mesic meadows, pastures, and edges of wetlands." Our records come primarily from hardwood forests, with most from mesic or bottomland habitats. Records from barrier islands and peatlands are lacking and we have only a small number from Longleaf Pine habitats, usually where there are stands of hardwoods located in nearby stream bottoms.
Larval Host Plants: Members of this genus are highly polyphagous, feeding on a wide range of herbaceous plants, with Dicots possibly preferred (Schmidt, 2009)
Observation Methods: Comes fairly well to blacklights, but usually in small numbers. The mouthparts are non-functional (Singer, 2000, cited in Schmidt, 2009), so it does not come to bait.

Status in North Carolina
Natural Heritage Program Status:
Natural Heritage Program Ranks: G5 [S5]
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands.
Comments: Occurs across most of the state and occupies a wide range of habitats; appears to be fairly secure
