【请大家支持我的潜叶虫网站http://www.sciencenet.cn/blog/entomology.htm，欢迎提供相关图片和资料】 看“粪”识潜虫 Identifying miners by frass 语云“闻香识美人”，就是通过间接的信息进行物种或者个体的鉴定。对于潜叶虫而言，潜道就是物种识别的最明显的证据。在野外要采集到具备活潜叶虫的叶子是比较难的，要么错过了季节，要么虫子直接就死在虫道里。但潜道一直都保留着，甚至可以到来年。 To know a beauty by her scent, that is to say, we can identify a species or an individual according to indirect information. As for leafminer, the trails (mines) are the most distict feature to aid identification. In the wild it is difficult to collect leaves with active miners, one reason may be that we miss the season, the other is that the larva died in the trail. However, the mine is there and will be kept until next year. 不同目的潜叶虫在叶子上作画的风格各具特色：鳞翅目蛾类的喜欢用虫粪形成的单线条绘制廊道或者斑块；而双翅目蝇类幼虫的粪便则形成平行的双线；与双翅目相比，膜翅目蜂类的粪便更多更黑；鞘翅目甲虫类则经常造成叶子的缺刻。 Leafminers from different orders have their unique styles of leaf drawing: Lepidopteral moths like to draw galleries or blotches with single frass lines, while Diptera flies usually draw two parallel frass trails. The mines of Hymenoptera wasps have more and darker frass than the mines of dipetrous flies. Coleoptera beetles always make cut-outs and holes in the leaves.
