Oligia chlorostigma (Harvey, 1876) - No Common Name


Taxonomy
Superfamily: Noctuoidea Family: NoctuidaeSubfamily: NoctuinaeTribe: ApameiniP3 Number: 932377.00 MONA Number: 9402.00
Comments: One of twelve species that are currently placed in this genus that occur in North America north of Mexico (Lafontaine and Schmidt, 2010), two of which have been recorded in North Carolina. Lafontaine and Schmidt (2010), however, consider true Oligia to be an Old World genus, with all New World species now placed in this genus needing to be re-assigned.
Identification
Field Guide Descriptions: Beadle and Leckie (2012)Online Photographs: MPG, BugGuide, BOLDTechnical Description, Adults: Forbes (1954)Technical Description, Immature Stages: Wagner et al. (2011)                                                                                 
Adult Markings: A medium-small, mottled fuscous and green Noctuid. The ground color is gray to brown, variably dusted with green; the orbicular, reniform, and claviform spots are typically filled with green, as is the terminal area. The antemedian and postmedian lines are black. The antemedian is edged with white above the inner margin and the postmedian has white bars on the anterior side at the costa and at the reniform. Hindwings are fuscous (Forbes, 1954).
Wingspan: 25 mm (Forbes, 1954)
Adult Structural Features: Male reproductive structures are described (but not illustrated) by Forbes (1954) and are distinctive.
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: A larva illustrated by Wagner et al. (2011) is green with narrow white subdorsal stripes, a wider spiracular stripe, and narrower subspiracular stripes. The head appears to be relatively small and unmarked (no detailed description is given).
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
Distribution in North Carolina
Distribution: All of our records come from the Mountains at relatively low elevations
County Map: Clicking on a county returns the records for the species in that county.

Flight Comments: Univoltine, with all of our records coming from June
Habitats and Life History
Habitats: Most of our few records all come from riparian habitats
Larval Host Plants: Feeds on grasses (Wagner et al., 2011), presumably boring into the culm
Observation Methods: Our records all come from lights, but other members of this genus come to bait as well

Status in North Carolina
Natural Heritage Program Status: W3
Natural Heritage Program Ranks: G4 SU
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands.
Comments: This species was considered rare by Forbes (1954) and locally common by Wagner et al. (2011). We have very few records for this species and most from somewhat specialized habitats. However, more needs to be learned about the exact host plant and habitat preferences for this species in North Carolina before we can accurately assess its conservation status.
