Geometridae: Geometer Moths of Hawai'i II

Geometridae is a very large family of moths (Order:Lepidoptera) consisting of 35,000 described species. The name is derived from the latin word 'geometra' which means 'earth-measurer', referring to the movement of the caterpillar larvae.  Although they are strikingly butterfly-like in appearance, they are in fact moths.  Male antennae are feathered, most of them fly at night and they have a frenulum linking the wings.  One of the more popular and endemic Hawaiian geometrids is Eupithecia sp. Species within this genus are carnivorous predators only in Hawaii, feeding on insects instead of plant matter like their non-native counterparts. These sit-and-wait predators have raptorial claws structured for holding their prey, and appendages on their abdomens for trigger response. Another endemic, but invasive species is the Koa moth (Scotorythra paludicola).  Historic outbreaks and population explosions have resulted in mass defoliation of mature Koa trees. Please do your part and help transcribe geometrid specimens from our insect museum.  This expedition of 641 tasks is fully transcribed and validated. This data resource is harvested periodically into the main occurrence index.

尺蛾科（Geometridae）是鳞翅目（Lepidoptera）下的大型蛾类类群，目前已被描述的物种达35000种。其学名源自拉丁语词汇“geometra”，意为“测地者”，用以指代其幼虫的移动姿态。尽管该类群外形与蝴蝶极为相似，但实则属于蛾类。雄蛾触角呈羽状，绝大多数种类于夜间活动，且具有连接双翅的翅缰（frenulum）。夏威夷地区较为知名的特有尺蛾物种为Eupithecia属（Eupithecia）物种：该属物种在夏威夷群岛为专性肉食捕食者，以昆虫为食，而非其非本地近缘类群所取食的植物组织。这类“坐等型”捕食者拥有特化用于夹持猎物的捕捉足，腹部附肢可触发捕食反应。另一种特有但已造成入侵危害的物种为寇阿相思树蛾（Scotorythra paludicola），历史上其种群爆发曾导致成熟寇阿相思树出现大规模落叶现象。请协助我们转录昆虫博物馆馆藏的尺蛾标本。本次包含641项任务的转录工作已全部完成并通过验证。该数据集资源将定期汇入核心生物出现记录索引。
