Idaea bonifata
(Hulst, 1887)
Fortunate Wave
Idaea bonifata, commonly known as the Fortunate Wave, is a small geometrid native to North America. The was first described by Hulst in 1887 under the basionym Eois bonifata. are characterized by their diminutive size with forewings measuring 6–7 mm in length. The species exhibits an extended period spanning March through October, with larvae feeding on decaying leaf matter and stored grains.

Identification
May be distinguished from other small geometrid moths by its specific wing pattern and size, though precise diagnostic features require examination of genitalia or detailed wing venation. The name 'bonifata' (Latin for 'fortunate') may allude to distinctive markings. Confirmation typically requires reference to original description or keys for North American Idaea species.

Appearance
A small with forewings measuring 6–7 mm in length. As a member of the Idaea, it likely exhibits the typical wave moth wing patterning characteristic of the Sterrhinae , though specific coloration and pattern details are not documented in available sources.
Habitat
Specific preferences are not documented. Based on the broad geographic distribution across diverse North American regions, the likely occupies varied terrestrial habitats including grasslands, woodlands, and disturbed areas where larval food sources occur.
Distribution
Recorded from twelve U.S. states: Arizona, California, Georgia, Illinois, Kentucky, Maryland, Nevada, New Mexico, Oklahoma, Pennsylvania, Tennessee, and Utah. Also present in Vermont. The distribution spans multiple ecological regions from the Southwest deserts to the Mid-Atlantic and Great Lakes areas.
Seasonality
are active from March to October, indicating a prolonged period possibly encompassing multiple or extended patterns.
Diet
Larvae feed on decaying leaves and stored grains. feeding habits are not documented.
Life Cycle
Complete with , larval, pupal, and stages. Specific details regarding number of per year, stage, or site are not documented.
Ecological Role
Larvae contribute to decomposition processes through consumption of decaying plant matter. Potential minor pest status in stored grain contexts.
Human Relevance
Minor potential economic significance due to larval feeding on stored grains. Otherwise of limited direct human importance.
