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: Macaria granitata is included in the conifer-feeding signaria species group by Ferguson (2008), of which M. pinistrobata, M. fissinotata, and M. signaria are the other members that occur in North Carolina (two others, M. marmorata and M. oweni, have also been doubtfully recorded).
Identification
Field Guide Descriptions: Covell (1984; as Semiothisa granitata)Online Resources: 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. M. 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 M. 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 Macaria 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.

Flight Comments: Appears to occur throughout the growing season, with peaks in late spring and late summer.
Habitats and Life History
Habitats: Both Pitch Pine and Scrub Pine are associated primarily with dry ridges and other upland habitats; Scrub Pine also occurs in a variety of successional habitats. In the Mountains, Macaria granitata occurs both on slopes and ridges as well as lower areas, such as New River State Park, where old field habitats are common. In the Piedmont, records come again from dry ridges, including monadnock habitats in the Uwharries, as well as dry barrens and successional habitats.
Larval Host Plants: Larvae are stenophagous, feeding solely on hard pines, particularly Pitch Pine (Pinus rigida) and Virginia Pine (P. virginiana) (Ferguson, 1974; Wagner et al., 2001; Ferguson, 2008; Maier et al., 2013). In North Carolina, its range extends well beyond the limits of Pitch Pine, which is confined to the Blue Ridge. Across the Piedmont, it probably feeds primarily on Virginia Pine. - View
Observation Methods: Comes well to 15 watt blacklights but we do not have any records from either bait or flowers.

Status in North Carolina
Natural Heritage Program Status:
Natural Heritage Program Ranks: G5 SNR [S3S5]
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands.
Comments: Although fairly narrow in its host plant preferences, granitaria feeds on fairly common to abundant species and occupies a fairly wide range of upland habitats, including successional stands. It also has a fairly wide geographic range in the state and appears to be secure.
