Clostera
Clostera is a genus of moths in the family Notodontidae, subfamily Pygaerinae, containing approximately 30 described species distributed across the Holarctic and Oriental regions. Multiple species, including C. anachoreta, C. anastomosis, C. fulgurita, and C. cupreata, are recognized as significant defoliators of poplar (Populus) trees in forestry contexts across China, India, Europe, and Japan. The genus has been extensively studied for its economic impact and as a target for biological control and Bt toxin research.
Clostera jocosa
Clostera jocosa is a species of prominent moth in the family Notodontidae, first described by Edwards in 1886. It belongs to the genus Clostera, which comprises moths commonly known as "chocolate-tip" or "prominent" moths due to their characteristic wing patterns. The species is documented in the Catalogue of Life and has very few observations on iNaturalist, suggesting it may be rare, underreported, or restricted in range. Like other members of its genus, it is presumed to have larvae that feed on willow or poplar (Salicaceae), though specific host records for this species have not been confirmed.
Clostera strigosa
striped chocolate-tip, drab tent-maker moth
Clostera strigosa is a moth species in the family Notodontidae (the prominents), described by Augustus Radcliffe Grote in 1882. It is known by two common names: the striped chocolate-tip and the drab tent-maker moth. The species is found in North America, with records from Canada (Alberta, Manitoba, Saskatchewan) and the United States (Vermont). The specific epithet 'strigosa' refers to the streaked or striped appearance typical of this species.
