Macaria granitata Guenée, [1858] - Granite Moth

Taxonomy
Superfamily: Geometroidea Family: GeometridaeSubfamily: EnnominaeTribe: MacariiniP3 Number: 910771.00 MONA Number: 6352.00 MONA Synonym: Semiothisa granitata
Comments: This is one of 73 species in this genus that occur in North America, with 17 species occurring in North Carolina. In the latest checklist of North American Lepidoptera (Pohl and Nanz, 2023), North American members of the genus Speranza and Epelis were treated as junior synonyms of Macaria.
Species Status: Granitata is included in the conifer-feeding signaria species group by Ferguson (2008), of which pinistrobata, fissinotata, and signaria are the other members that occur in North Carolina (two others, marmorata and oweni, have also been doubtfully recorded).
Identification
Field Guide Descriptions: Covell (1984; as Semiothisa granitata)Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Ferguson (2008)Technical Description, Immature Stages: Maier et al. (2013)                                                                                 
Adult Markings: Similar to other Macaria in their angled hindwings and sub-falcate forewings, but members of this species group are distinguished from all other North Carolina Macaria in possessing a grayish rather than a yellowish head (Forbes, 1948). All members of this group are generally similar in their pattern of lines and spots. Granitata is the most mottled member of this group, with strong contrasts between the gray basal area, white or cream area between the median and postmedian lines, and the dark gray subterminal area. All lines and spots are well-marked, with the postmedian being waved and undulate rather than straight; the median and antemedian lines are often jagged or dentate. The large pre-apical spot at the costal end of the subterminal line is usually reddish-brown rather than the darker brown or black spot typical of pinistrobata, which can otherwise be very similar in appearance (see Ferguson, 1974, 2008, and Covell, 1984, for details).
Adult Structural Features: All members of the signaria group have males with foveae (Ferguson, 2008).
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: Larvae are blue-green with pale lateral stripes and a dark dorsal surface; the head is green with dark brown markings (Maier et al., 2013). The blue-green color and dark mid-dorsal line help distinguish granitata from two other species of Macaria that feed on hard-pines: M. transitaria and M. bicolorata (Maier et al., 2013).
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
Distribution in North Carolina
Distribution: This is the only member of this species group whose range extends well into the Piedmont. It has not been recorded in the Coastal Plain, however, including areas where Pond Pine (P. serotina), a close relative of Pitch Pine, occurs.
