蒙古阿尔泰山脉的溪流主要来自冰川，由于海拔高，气温低，年降水量少，对蜉蝣来说是极端的条件。蒙古阿尔泰地区的蜉蝣种类有8科、26属、亚属、38种。研究材料完全是imagos，在2008年，2009年和2010年蒙古水生昆虫调查领导的考察期间从78个地点收集。Raptobaetopus tenellus、Caenis luctuosa和C. rivulorum为蒙古区系新记录，Ameletus montanus，Baetis为蒙古区系新记录（Acentrella）lapponica，Baetis sibiricus，Baetis（Labiobaetis）attrebatinus，Centroptilum luteurs，Procloeon pennulatum，Ephemerella aurivillii，Serratella setigera，Ephemera sachalinensis，Ecdyonurus（Afronurus）abracadabrus、Cinygmula kurenzovi、Ecdyonurus（Afghanurus）vicinus和Epeorus（Belovius）pellucidus来自蒙古阿尔泰地区。该地区最常见的物种是Vernus和Ephemerella aurivillii。
Streams in the Mongolian Altai Mountains are mostly fed from glaciers and are extreme conditions for mayflies because of high elevation, low temperatures and low annual precipitation. Previous information about mayflies of Western Mongolia is scarce, but with this study a total of 38 species belonging to 26 genera and subgenera and 8 families of mayflies has been recorded in the Mongolian Altai region. Study material was entirely imagos and collected from 78 sites during expeditions led by the Mongolian Aquatic Insect Survey in 2008, 2009 and 2010. Raptobaetopus tenellus, Caenis luctuosa and C. rivulorum are recorded as new to the fauna of Mongolia, and there are new distribution records for Ameletus montanus, Baetis (Acentrella) lapponica, Baetis sibiricus, Baetis (Labiobaetis) attrebatinus, Centroptilum luteolum, Procloeon pennulatum, Ephemerella aurivillii, Serratella setigera, Ephemera sachalinensis, Ecdyonurus (Afronurus) abracadabrus, Cinygmula kurenzovi, Ecdyonurus (Afghanurus) vicinus and Epeorus (Belovius) pellucidus from the Mongolian Altai region. Baetis vernus and Ephemerella aurivillii are the most frequently encountered species in this region.
