Drosophilid
Guides
Chymomyza amoena
A Nearctic drosophilid fruit fly native to eastern United States forests. It has established as an invasive species in Europe since its discovery in former Czechoslovakia in 1975, subsequently spreading to Switzerland, Italy, and German border regions. The species exhibits a distinctive ecological strategy: breeding in damaged or parasitized nuts and fruits rather than relying solely on fermenting substrates. This behavioral constancy for interspecies dependency—exploiting substrates pre-conditioned by other insects—has enabled it to occupy a vacant niche in European ecosystems.
Hyalistata
Hyalistata is a genus of small flies in the family Drosophilidae, described by Wheeler in 1960. It belongs to the subfamily Steganinae and tribe Gitonini, placing it within a group of drosophilids often associated with decomposing plant matter and fungal substrates. The genus is characterized by distinctive morphological features of the head and wing venation. Species within Hyalistata are poorly known and rarely encountered in general collections.
Mycodrosophila claytonae
Mycodrosophila claytonae is a species of fruit fly in the family Drosophilidae, first described by Wheeler and Takada in 1963. It belongs to the genus Mycodrosophila, a group of drosophilid flies often associated with fungal substrates. The species is documented in scattered observations, with 44 records on iNaturalist. Like other members of its genus, it likely has ecological ties to decaying fungal matter.
Scaptomyza adusta
Scaptomyza adusta is a species of fruit fly in the family Drosophilidae. It is native to Europe, with confirmed records from Great Britain and the Canary Islands, and doubtful records from Belgium and France. The species was originally described as Drosophila adusta by Loew in 1862 and later transferred to the genus Scaptomyza. Like other members of its genus, it belongs to a lineage of drosophilids that has undergone evolutionary transitions in feeding ecology.
