Hawaiian Drosophilidae: Modified Mouthparts

The diverse Drosophila of Hawai'i consists of four main lineages. The largest of these four clades is the polyphagous modified mouthparts drosophila, which are morphologically and ecologically distinct. All 106 described species are endemic to the Hawaiian Islands and exhibit modifications of the labellum (mouth) for courtship and feeding purposes. Although the larvae breed on stems, fruits, flowers and bark of a variety of host families, most are substrate and host-specific. Being the largest of the four lineages, it is surprising that it is also the most poorly studied. Please contribute and transcribe the modified mouthpart specimens of the Insect Museum.This expedition of 563 tasks is fully transcribed and validated.

夏威夷群岛分布的多样果蝇属（Drosophila）类群包含4个主要演化支。其中体量最大的演化支为多食性特化口器果蝇类群，该类群在形态与生态上均独具特色。目前已正式描述的106个物种均为夏威夷群岛特有种，它们的唇瓣（labellum）特化以适配求偶与取食需求。尽管该类群的幼虫可寄生于多种寄主科植物的茎秆、果实、花朵与树皮中，但多数物种具有严格的底物与寄主专一性。作为4个支系中规模最大的类群，该演化支却是目前研究程度最低的类群。敬请协助转录该昆虫博物馆馆藏的特化口器果蝇标本。本次涵盖563项任务的项目已完成完整转录与验证工作。
