Blurry Chocolate Angle
Macaria transitaria is a small geometrid commonly known as the blurry chocolate angle. It is native to North America and recognized by its relatively compact wingspan of 23–26 mm. The is associated with pine forests, as its larvae feed on Pinus species.

Identification
Distinguished from other Macaria by the combination of small size (23–26 mm wingspan) and North American distribution. The "blurry" quality of its wing patterning may separate it from more sharply marked , though precise diagnostic characters require examination of genitalia or reference to specialized geometrid keys.

Appearance
Small with wingspan of 23–26 mm. The "blurry chocolate angle" suggests brownish wing coloration with indistinct patterning, though specific markings are not documented in available sources.
Habitat
Associated with pine-dominated forests and woodlands, given larval relationship with Pinus .
Distribution
North America. Specific records include the northeastern United States (Vermont).
Diet
Larva feeds on Pinus (pines). feeding habits are not documented.
Host Associations
- Pinus - larval plant-level feeding confirmed; specific Pinus not documented
Ecological Role
Larval herbivore on pine trees; contributes to nutrient cycling in coniferous forest .
Similar Taxa
- Macaria bisignata (Red-headed Inchworm)Similar size and preference; M. bisignata has more distinct markings and different larval preferences
- Other Macaria speciesMany share brown coloration; accurate identification requires examination of wing pattern details or genitalia
