摘要
The genus Calyptra Ochsenheimer is known for its atypical behavior of exhibiting both obligate fruit piercing and facultative blood feeding as adults. The genus has been reported piercing a vast array of fruits including Citrus, figs, grapes, and raspberries. One species, Calyptra canadensis (Bethune), more commonly known as the Meadow Rue Owlet moth, is the only member of the genus known to occur in the New World. The extent of this species' range, along with its adult host breadth, remains unknown. Museum specimens of C. canadensis from 20 institutions and private collections were examined and georeferenced to generate the most comprehensive distribution map for the species to date. Locality data was analyzed to explore the phenology of C. canadensis, recovering an adult activity period from May to October. Larval rearing experiments were also undertaken, documenting the presence of five larval instar stages and a development time ranging from 6 to 8 weeks. Overall this study expands what is currently known about the biology of C. canadensis, specifically its larval development, adult distribution, and activity period.
