Macaria granitata, known as the granite or granite angle, is a small geometrid moth with a wingspan of approximately 25 mm. It occurs in the eastern United States and southern Canada, with larvae specialized on hard pines, particularly Pinus rigida. The has one to two per year depending on location.

More Details

Host specificity notes

Larval records show geographic variation: strict Pinus rigida association in New England versus broader hard pine use in southern New Jersey. This may reflect local pine composition rather than intrinsic dietary flexibility.
