Asteiidae Flies of Hawai'i

Asteiidae is a very small family of flies, consisting of about 130 described species from 10 widespread genera. Because of their small size as a family, specimens are rarely collected in the wild. Flies are 1 to 3 millimeters in length, are relatively thin-bodied and exhibit a yellow-black or other dark colored hue. Unlike females, males have distinct frontal stripes. Adults from some species exhibit host preference, while others can be found on a range of hosts and substrates, from flowers to window screens. The larval biology of this family is still a mystery but past research suggests that the larvae may scavenge and feed during the feeding of other insects. Another notable characteristic displayed by Asteiidae flies is that they are acalyptrate, or are not blood-feeders. Please help transcribe the UHIM's Asteiidae fly collection in order to better help us understand their distribution and impact in Hawai'i.This expedition of 721 tasks is fully transcribed and validated. This data resource is harvested periodically into the main occurrence index.树蚤蝇科（Asteiidae）是一类体型极小的蝇类科，包含约130个已描述物种，隶属于10个广布属。由于该类群整体体型微小，野外标本极少被采集。该科蝇类体长1至3毫米，躯体相对纤细，体色多呈黄黑或其他深色色调。与雌性个体不同，雄性个体具有清晰的额条纹（frontal stripes）。部分物种的成虫具有寄主偏好，而另一些则可在多种寄主与基质上被发现，涵盖花朵至纱窗等多种场景。该科幼虫的生物学特性至今仍是谜团，但过往研究表明，其幼虫可能在其他昆虫取食期间进行腐食性取食。树蚤蝇科的另一显著特征为无腋瓣类（acalyptrate），且均不吸血。请协助转录UHIM所藏的树蚤蝇科蝇类标本馆藏，以助力我们更好地了解该类群在夏威夷的分布与影响。本次共完成721项任务的完整转录与验证工作。本数据集资源将定期同步至主物种出现记录索引。
