Samples of dipteran larvae were collected from live sheep throughout Scotland, reared in the laboratory, and identified once adult flies emerged. Lucilia sericata was found in 77% of samples, and other species in 49%. The most common alternative species were L.caesar, which occurred in 31% of samples, and Protophormia terraenovae, which occurred in 18%. Three other calliphorid species, Calliphora vomitoria, C.vicina and L.illustris, and the muscid Muscina pabulorum were also found. The proportion of samples containing alternative species was significantly lower in eastern Scotland than in western Scotland. Significantly higher proportions of samples containing alternative species were collected at altitudes of 200m and above; from sheep of hill breeds; from rough grazing conditions and moorland; in the absence of trees; and in the presence of bracken.
在苏格兰各地从活羊身上采集双翅目幼虫样本，在实验室饲养，待成年苍蝇羽化后进行鉴定。在77%的样本中发现了丝光绿蝇，49%的样本中发现了其他物种。最常见的其他物种是在31%的样本中出现的凯撒绿蝇和在18%的样本中出现的新陆原伏蝇。还发现了另外三种丽蝇科物种，即反吐丽蝇、红头丽蝇和亮绿蝇，以及蝇科的巴氏家蝇。在苏格兰东部，含有其他物种的样本比例明显低于西部。在海拔200米及以上地区；从山地品种的绵羊身上；在粗放放牧条件和高沼地；没有树木的地方；以及有蕨类植物的地方采集到的含有其他物种的样本比例明显更高。
