Taxonomy
Superfamily: Noctuoidea Family: ErebidaeSubfamily: ErebinaeTribe: EuclidiiniP3 Number: 930932.00 MONA Number: 8750.00
Comments: A wholly American genus containing 12 species from North and South America. As currently constructed the genus is polyphyletic and some species will eventually be moved elsewhere. There are 7 species found in North America and 3 in North Carolina.
Species Status: Specimens from North Carolina have been sequenced and are similar to those from elsewhere. No evidence for hidden species exists.
Identification
Field Guide Descriptions: Covell (1984)Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Forbes (1954)Technical Description, Immature Stages: Forbes (1954); Crumb (1955); Wagner et al. (2011)                                                                                 
Adult Markings: Similar in size and pattern to Ptichodis bistrigata and vinculum; all three species possess strongly contrasting yellow and dark antemedian and postmedian lines. Male herbarum are easily distinguished from the other two by their possession of a dark spot located in the basal area just in front of the antemedian line near the inner margin. Both sexes of vinculum can also be easily distinguished by their possession of a dark apical spot that is not present in herbarum or bistrigata. Females of herbarum are likely to be confused only with P. bistrigata, but can be identified by the placement of the yellow and black lines making a wedge in the middle of the wing. In P. bistrigata the inner lines (facing each other) are both black. In P. herbarum one is black, the other yellow.
Wingspan: 28 mm (Forbes, 1954)
Adult Structural Features: Genitalia: In the female the ostial plate is broadly triangular but squarish in P. vinculum and insignificant in P. bistrigata. The male genitalia are similar to those of P. vinculum but the uncus is noticeably divided and the costa of the valva does not have a broad bump in the middle.
Structural photos
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: Larvae are similar to other members of this tribe (Euclidiini), having long, spindle-shaped bodies -- widening towards the middle -- and marked with a series of fine stripes. Crumb (1955) describes features that can be used to distinguish herbarum from species of Caenurgia and Caenurgina, but until the larvae of other members of Ptichodis are described, it is uncertain how to distinguish among these three.
Larvae ID Requirements: Identifiable only through rearing to adulthood.
Distribution in North Carolina
Distribution: Found throughout much of the state though rarely common. Particularly uncommon to rare in the western Piedmont and Mountains.
