Scaptodrosophila

Duda, 1923

Scaptodrosophila is a large of fruit flies in the Drosophilidae, comprising over 250 described distributed across multiple continents. The genus exhibits considerable diversity in Australia, where multiple species groups have been studied for their courtship and -plant associations. Some species are specialized flower-breeders, with documented cases of host-race formation on Hibiscus species. The genus has been subject to taxonomic revision in multiple regions including India and Australia.

Habitat

varies by ; some species are specialized to breed in flowers of Hibiscus species (section Furcaria).

Distribution

Widely distributed across multiple continents including Australia (where multiple groups are ), India, and parts of Europe (records from Denmark, Norway, Sweden). Two centers of diversity for the coracina group in Australia: south-eastern Queensland (11 species) and the region around Cairns (8 species).

Host Associations

Hibiscus - breeding sitesection Furcaria; documented for S. hibisci and S. aclinata

Behavior

Male courtship in Australian involves wing vibration, tapping, and licking ; species-specific courtship songs and visual displays have been documented. Behavioral differences exist between the lativittata and fumida species groups. -plant specialization has been observed, with early stages of host-race formation in S. hibisci breeding on different Hibiscus species in close proximity.
