They also found that the water became well aerated and that populations of important food-chain insects such as mayflies, stoneflies and caddisflies grew.───他们也发现河水的通气性良好，重要的食物链昆虫像是蜉蝣、石蝇和石蛾的族群数都增加了。

The body size of leptophlebiid mayflies are usually very small, many microscopical and SEM structures have been employed in previous work.───细裳蜉科蜉蝣个体较小，对本科的研究又相对较深入，很多情况下要用到极细微结构特征。
Millions upon millions of mayflies take to the air for a single devastating act to mate and then die.───数以百万计的蜉蝣飞向空中，执行一项致命任务。

The other main type of life-cycle is followed by insects such as the aphids, grasshoppers, dragonflies and mayflies.
The nymphs, or first larval stages of mayflies, are also adapted to very particular conditions.
Phylogeny and higher classification of mayflies, feeding habits of nymphs, relationship with other insects, paleoecology and important value in biostratigraphic correlation are briefly summarized.
At the end of that time, the team found higher populations of stoneflies, mayflies and caddis flies in the screened segments than in adjacent unscreened ones.
The hypothesized function of subcostal brace in mayflies is to strengthen the connection between distantly separated longitudinal veins because of sclerite plate at radius vein base.
