Thaumatopsis edonis (Grote, 1880) - No Common Name


Taxonomy
Superfamily: Pyraloidea Family: CrambidaeSubfamily: CrambinaeTribe: CrambiniP3 Number: 800849.00 MONA Number: 5438.00
Identification
Field Guide Descriptions: Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Fernald (1896).]                                                                                 
Adult Markings: This is a rather distinctive species due to its coloration and patterning, large size for a Crambini, and pectinate antennae that are held upwards when an individual is resting. The head and thorax are light reddish-brown, the large palps vary from light brown to reddish-brown, and the prominent antennae are dark brown and bipectinate in the males. The forewing has a prominent, diffuse pink or salmon-colored streak along the costal and subcostal region of the wing that extends from near the wing base to the outer margin. The veins are concolorous with the streak, except for a whitish middle vein that extends from the wing base before fading at around two-thirds the wing length. The areas between the veins and dorsal to the pink streak are heavily shaded with varying amounts dark brown. The termen has a line of four five faint brown dots, and the fringe is brown overall with three or four finely striated brown lines within. The hindwing is pale brown with a paler fringe.
Wingspan: 34-36 mm (Fernald, 1896).
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: The larval life history is undocumented.
Distribution in North Carolina
Distribution: Thaumatopsis edonis appears to be an uncommon but broadly distributed species, with scattered records across much of the eastern U.S. The range extends from Maine to southern Florida and westward to central Texas, central Oklahoma, Arkansas, Missouri, and Kentucky, with one isolated record from northern Nebraska.

Flight Comments: Local populations appear to be univoltine throughout the range with a brief flight season centered on September and October. The adults have been observed from August through November in different areas of the range. As of 2023, our records are from late-September through mid-October.
Habitats and Life History
Habitats: All of our records are from the Sandhills and mostly from fire-maintained Longleaf Pine forests, with a few sites in the vicinity of seeps or headwater streams. The sites typically have well-developed ground vegetation with a diverse mix of grasses and forbs.
Larval Host Plants: The host plants are undocumented. - View
Observation Methods: The adults are attracted to lights and can be flushed from ground vegetation and netted.
