Sutyna privata (Walker, 1857) - No Common Name

Taxonomy
Superfamily: Noctuoidea Family: NoctuidaeSubfamily: NoctuinaeTribe: XyleniniP3 Number: 932707.00 MONA Number: 9989.00
Comments: A New World genus of 3 species of which one is found in the United States and in North Carolina. The other two are from South America and may not be closely related to our species. Several North American forms of privata that were previously treated as separate species -- teltowa, profunda, and tenuilinea (see Forbes, 1954; Hodges et al., 1984) -- are now considered to be just forms of privata (Lafontaine and Schmidt, 2010).
Species Status: Although no specimens from North Carolina have been barcoded, one from Florida is very similar to those from across Canada and it is unlikely that significant heterogeneity exists.
Identification
Field Guide Descriptions: Beadle and Leckie (2012)Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIFTechnical Description, Adults: Forbes (1954), as Antytus privatusTechnical Description, Immature Stages: Wagner et al. (2011)                                                                                 
Adult Markings: This large, bluish-black, fall-flying Noctuid is likely to be confused only with Xylotype capax, which is similar in size, color, and pattern and whose flight period overlaps. Our populations of privata (matching Forbes' description of teltowa) are much darker, however, and are smoother in appearance. They also lack the dark anal dash found in capax and the well-defined, white subterminal line, but show more contrast between the pale grayish area located before the subterminal and the mainly dark terminal area; in capax these areas are primarily concolorous. Sexes are similar.
Adult Structural Features: In the male, the valves are very blunt and the aedeagus tip is heavily sclerotized and has several spines. In the female, the bursa has 4 ribbon-like signa similar to those found in Metaxaglaea. These characters should separate this species from anything likely to be confused with it.
Structural photos
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: As illustrated in Wagner et al. (2011), larvae are green or brown, with fine lines on the upper surface and a broad, pale spiracular line bordered by a narrow, dark stripe above.
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
Distribution in North Carolina
Distribution: Found throughout the Piedmont and Coastal Plain
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: Apparently on the wing for about two weeks in September and October
Habitats and Life History
Habitats: Most of our records come from the Coastal Plain, primarily from Longleaf Pine sandhills and flatwoods habitats, as well as dry stands of hardwoods. Blackberry is not common in most of these habitats but Blueberries and Huckleberries are frequent. Our few records from the Piedmont also come from fairly dry woodlands, including a stand of Piedmont Longleaf Pine Forest, where Blueberries again are common.
Larval Host Plants: Although this species may be a general feeder, caterpillars have been found only on Blackberry (Rubus sp.) and Blueberry (Vaccinium sp.) (Wagner et al., 2011; Sullivan, pers. obs.).
Observation Methods: Comes to light but response to bait unknown. Its flight period in early September is when few people put out bait for moths.

Status in North Carolina
Natural Heritage Program Status:
Natural Heritage Program Ranks: G5 [S3S4]
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands.
Comments: Most of our records come from fairly open habitats where Blueberries are common. Old Field and other disturbed habitats where Blackberries are common have not been as well-sampled, however, and their use by this species needs to be checked before its conservation status can be determined.
