Operaciniinae

Operaciniinae is a subfamily of moths belonging to the family Geometridae. This group is characterized by their distinctive wing patterns and is found primarily in the Neotropical region, with a few species occurring in the Nearctic and Afrotropical regions. The subfamily includes approximately 13 genera and over 100 species, with the majority belonging to the genus Operacinis.

The larvae of Operaciniinae are known for their specialized feeding habits. Many species are associated with the leaves of their host plants, often feeding on the underside of the leaves. Some species are also known to feed on the flowers of their host plants. The host plants for these moths are diverse and include a variety of plant families, such as Asteraceae, Fabaceae, and Malvaceae.

The adult moths of Operaciniinae are typically medium to large in size, with a wingspan ranging from 25 to 50 millimeters. They are known for their distinctive wing patterns, which often include a combination of dark and light colors, as well as intricate patterns and markings. The forewings are usually broader than the hindwings, and the venation is characteristic of the family Geometridae.

The taxonomy of Operaciniinae is still a subject of ongoing research, with some species and genera being revised and redescribed in recent years. The subfamily is of interest to both taxonomists and lepidopterists due to its unique characteristics and the specialized feeding habits of its larvae.
