Lytrosis heitzmanorum Rindge, 1971 - No Common Name

view caption
Superfamily: Geometroidea Family: GeometridaeSubfamily: EnnominaeTribe: AngeroniniP3 Number: 911147.00 MONA Number: 6722.00
Comments: This strictly North American genus contains four species all of which occur in North Carolina.
Species Status: Barcodes indicate a single species since North Carolina specimens barcode as conspecific with those of the mid-west. All of our species are easily separable using barcoding.
Field Guide Descriptions: Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLD                                                                                 
Adult Markings: One of three very similar species which have been confused frequently, but which can be distinguished by following the course of the postmedian line on the forewing. If it is straight, the species is L. unitaria, if it is wavy it is either L. sinuosa or L. heitzmanorum. Then check the hindwing and look for a black, somewhat broad median line indicating it is L. heitzmanorum and not L. sinuosa.
Adult Structural Features: As with the related genus Euchlaena, the genitalia rarely have clearcut differences; the genitalic features given in the review of the genus (Rindge, 1971) do not work well.
Structural photos
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: Life history is unknown.
Distribution in North Carolina
Distribution: Originally described from the mid-west, we have recently obtained records from both the foothills of the Blue Ridge and the Piedmont in North Carolina. We have not yet found any from the Coasrtal Plain where L. sinuosa appears to be restricted. Mountain records unknown but would not be unexpected at lower altitudes; eastern boundary unknown.
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)

Habitats and Life History
Habitats: Found in oak-hickory forests in the western Piedmont of the state.
Larval Host Plants: Unknown but presumably an oak feeder.
Observation Methods: Comes to lights readily but probably not to bait. Has a short flight period so without the new moon during its flight period, it can easily be missed.
Status in North Carolina
Natural Heritage Program Status: W3
Natural Heritage Program Ranks: GNR SU
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands.
