The genus Stylogaster Macquart (Diptera: Conopidae) is sister to the remainder of the Conopidae. While all other Conopidae are endoparasitoids of aculeate Hymenoptera, species of Stylogaster appear to be endoparasitoids of ‘orthopteroids’, as the only confirmed rearing records are from crickets and cockroaches. Many calyptrate flies have been observed with Stylogaster eggs attached, but since no Stylogaster have been reared from any dipterans, it is still unknown if these flies are hosts, results of accidental oviposition or carry the eggs to the actual hosts. In this study, we report our findings of Stylogaster eggs on blow flies (Calliphoridae) attracted to millipede defence secretions in Tanzania. Out of seven different species collected and a total of 301 specimens, only flies of the genus Tricyclea Wulp had Stylogaster eggs attached. Out of 133 Tricyclea collected, 32 (24%) had Stylogaster eggs attached and, with one exception, all eggs were attached to the abdomen. The lifecycle of Stylogaster is summarised and discussed with a particular focus on dipteran egg-carriers.

在坦桑尼亚，丽蝇身上的卵被千足虫的防御分泌物吸引，试图总结它们的生物学（双翅目：Conopidae 和 Calliphoridae）。


Stylogaster Macquart 属（双翅目：Conopidae）是其余 Conopidae 的姐妹。虽然所有其他 Conopidae 都是有刺膜翅目的内寄生蜂，但 Stylogaster 的物种似乎是“直翅类”的内寄生蜂，因为唯一确认的饲养记录来自蟋蟀和蟑螂。人们观察到许多有耳蝇卵附着有细叶蝇卵，但由于没有任何双翅目昆虫饲养过细叶蝇，因此仍不清楚这些苍蝇是否是宿主、意外产卵的结果或将卵携带给真正的宿主。在这项研究中，我们报告了坦桑尼亚丽蝇（Calliphoridae）上被千足虫防御分泌物吸引的柱蝇卵的发现。在收集的 7 个不同物种和总共 301 个标本中，只有 Tricyclea Wulp 属的苍蝇附着了 Stylogaster 卵。在收集的 133 辆三轮车中，有 32 辆（24%）附着有斯泰洛斯特的卵，除了一颗例外，所有卵都附着在腹部。总结和讨论了 Stylogaster 的生命周期，特别关注双翅目卵载体。
