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. This data resource is harvested periodically into the main occurrence index.

夏威夷多样的果蝇属（Drosophila）物种包含四大主要演化支系。四大演化支中规模最大的一支为多食性特化口器果蝇类群，该类群在形态学与生态学层面均具有鲜明特异性。该类群共计106个已描述物种，均为夏威夷群岛特有种，其唇瓣（labellum，即口器）特化以满足求偶与取食需求。尽管该类群幼虫以多种寄主类群的茎秆、果实、花朵及树皮为繁育基质，但多数物种仍具有严格的生境与寄主专一性。作为四大演化支中规模最大的类群，该类群却也是研究程度最低的类群，这一情况颇为出人意料。诚邀各界人士协助转录昆虫博物馆馆藏的特化口器标本。本次涵盖563项任务的相关项目已完成全部转录与验证工作。该数据集资源将定期汇入主物种出现索引数据库。
