Calluga is a genus of moths in the family Geometridae, subfamily Larentiinae. The genus was erected by entomologist William Warren in 1902. Species within Calluga are characterized by slender bodies and wings that typically display muted colors such as browns, grays, and ochres, often with subtle patterning that provides camouflage against bark and foliage. Like other geometrid moths, the larvae (caterpillars) are known as inchworms due to their characteristic looping gait.
Taxonomy
- Kingdom: Animalia
- Phylum: Arthropoda
- Class: Insecta
- Order: Lepidoptera
- Family: Geometridae
- Subfamily: Larentiinae
- Genus: Calluga Warren, 1902
Recognized Species (selected)
- Calluga costalis (Walker, 1866) – distributed in South and Southeast Asia.
- Calluga spilonota (Walker, 1862) – recorded from India, Sri Lanka, and surrounding regions.
- Calluga simplicia (Warren, 1896) – found in the Australasian realm, including New Guinea.
- Calluga tricolorata (Hampson, 1895) – occurs in the Indian subcontinent.
Geographic Distribution
Members of the genus are primarily found throughout the Oriental and Australasian biogeographic zones. Their range includes the Indian subcontinent, Southeast Asia, parts of the Malay Archipelago, and extending to New Guinea and surrounding islands.
Biology and Ecology
Adults are nocturnal and are attracted to light sources, a behavior typical of many geometrid moths. The larvae feed on a variety of host plants, though specific plant associations are not comprehensively documented for all species. As with other geometrids, the pupal stage occurs in a loosely constructed cocoon in leaf litter or soil.
Research and Significance
The genus Calluga has been referenced in taxonomic revisions and faunal surveys of Lepidoptera in its native regions. Its species contribute to biodiversity assessments and are of interest in studies of nocturnal pollination and ecosystem monitoring.
