| 中文摘要: |
| 食蚜蝇作为蚜虫重要的捕食性天敌，其捕食蚜虫的虫态是幼虫期。针对目前研究以描述食蚜蝇成虫的形态特征进行种类鉴定为主，而对卵及幼虫的描述却很少的现状，采集野外2种常见的食蚜蝇——斜斑鼓额食蚜蝇（Scaevapyrastri）和黑带食蚜蝇（Episyrphusbalteata），对其卵、幼虫、蛹及成虫4个虫态进行描述，并提供彩色照片，这对于其早期鉴定极为重要。 |

| Abstract: As an important predatory natural enemy, Syrphidae mainly preyed on the larval stage. According to the current situation that the morphological characteristics of adults of Syrphidae were mainly described, but the description of eggs and larvae were very few, two kinds of common Syrphidae (Scaeva pyrastri and Episyrphus balteata) were collected from the field. It was very important for the early identification to describe the insect states (eggs, larvae, pupae and adults) and provide relevant colour pictures. |
