Summary

Ennominae is the largest subfamily of the Geometridae family, containing around 9,700 described species. Its notable characteristic is the absence of an M2 vein in the hindwings, and many species serve as defoliating pests.

Physical Characteristics

Most species are fairly small, with colors that vary; many are gray. The distinguishing characteristic is the lack of an M2 vein in the hindwing.

Identification Tips

Look for moths lacking the M2 vein in the hindwings, with color variations commonly including gray. Identification below the subfamily level may require dissection or DNA testing.

Habitat

Global distribution; habitats range widely, including temperate and tropical regions.

Distribution

Approximately 9,700 described species worldwide, with 751 species in North America.

Diet

Many species are known defoliating pests, which indicates a herbivorous diet, often feeding on leaves.

Life Cycle

Typically, the life cycle includes egg, larva (caterpillar), pupa, and adult stages, though specifics may vary by species.

Ecosystem Role

Some species play significant roles as defoliators in ecosystems, contributing to plant population dynamics.

Economic Impact

Includes species that are notorious defoliating pests; potential agricultural impacts due to larval feeding behavior.

Evolution

Described as first appearing in the Eocene epoch, with recent findings including fossil evidence from Baltic amber.
