Acrobasis caryae Grote, 1881 - Hickory Shoot Borer Moth


Taxonomy
Superfamily: Pyraloidea Family: PyralidaeSubfamily: PhycitinaeTribe: PhycitiniP3 Number: 800156.00 MONA Number: 5664.00
Species Status: "All Acrobasis with a 3 are very tricky for ID. In some cases it requires a close look at male antennae, in others a look at the underside of the wings in males. In some cases females cannot be distinguished (e.g. A. angusella and A. latifasciella)" (Scholtens, 2017).
Identification
Field Guide Descriptions: Beadle and Leckie (2012)Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Neunzig (1996)Technical Description, Immature Stages: Neunzig (1972)                                                                                 
Adult Markings: The ground color of the forewings is typically dark fuscous, with base and median area concolorous; some southern individuals may be paler gray (Forbes, 1923; Heinrich, 1956). A transverse, black scale ridge is located in the antemedial area, preceded with whitish scaling and followed by a slender, pale, pinkish or ochraceous line. Apart from the pale line beyond the scale ridge, no other yellowish or pinkish shading exists. A pale subterminal line typically is present but sometimes obscure. A pair of separated discal dots is also present but not strongly contrasting with the ground color. Males have a short black patch at the base of the costa on the dorsal surface of the forewings and a long black streak along the top of the cell on the underside. Hindwings are smoky fuscous.
Wingspan: 18-20 mm (Heinrich, 1956)
Adult ID Requirements: Identifiable from photos showing hindwings, abdomen, or other specialized views [e.g., frons, palps, antennae, undersides].
