Acronicta lobeliae Guenée, 1852 - Greater Oak Dagger


Taxonomy
Superfamily: Noctuoidea Family: NoctuidaeSubfamily: AcronictinaeP3 Number: 931455.00 MONA Number: 9238.00
Comments: One of 74 species in this genus found in North America north of Mexico (Schmidt and Anweiler, 2020), 42 of which have been recorded in North Carolina. This species is placed in subgenus Agriopodes by Schmidt and Anweiler, and in the Hasta Species Group. Other members of this group in North Carolina include hamamelis, lithospila, innotata, betulae, radcliffei, hasta, interrupta, laetifica, spingigera, superans, and morula.
Identification
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONATechnical Description, Adults: Forbes (1954); Schmidt and Anweiler (2020)                                                                                 
Adult Markings: A large, pale gray dagger with three strong dashes and a thick bar connecting the reniform and orbicular spots (Forbes, 1954). Larger than either A. hasta or A. laetifica; the forewing length in lobeliae is > 21 mm but barely over 20 mm in the other two (Schmidt and Anweiler, 2020). Acronicta hasta is also usually darker gray, has a thicker but shorter basal dash, and has a weaker or absent apical dash (Forbes, 1954). Acronicta laetifica has a whiter ground color and finer, more contrasting dashes. Some individuals of lobeliae are difficult to distinguish from the other two species based on photographs alone; measurements of the forewing are always helpful.
Wingspan: 50 mm (Forbes, 1954)
Forewing Length: 22.8 mm, males; 25 mm, females (Schmidt and Anweiler, 2020)
Adult ID Requirements: Identifiable from photos showing hindwings, abdomen, or other specialized views [e.g., frons, palps, antennae, undersides].
