Potential biological threats to honey bees must be identified quickly, before making disruptive and costly decisions. Here we describe numerous Osmia cornifrons (Hymenoptera: Megachillidae) cocoons in honey bee cells from one bee hive in Ohio. The developing Osmia cells presented themselves as a mystery at first, catching the attention of regulatory agencies. Along with identifying this species as a presumably benign resident in honey bee colonies, our observations suggest Osmia may use stored honey bee resources to provision offspring. Conceivably, resident honey bees might even act as surrogates because Osmia cocoons were attached to one another with honey bee wax, it seems likely that honey bee hosts were present during Osmia development. Along with resolving a potentially new biotic threat to honey bees, this diagnosis suggests a method for mass production of Osmia pollinators using an array of single-cell foundation.

在蜜蜂梳状细胞上发现的异常茧被发现是 Osmiacornifrons (Radoszkowski)（膜翅目：Megachillidae）

在做出破坏性和代价高昂的决定之前，必须迅速确定对蜜蜂的潜在生物威胁。在这里，我们描述了来自俄亥俄州一个蜂巢的蜜蜂细胞中的大量 Osmia cornifrons（膜翅目：Megachillidae）茧。开发中的 Osmia 细胞起初是个谜，引起了监管机构的注意。除了将这个物种确定为蜜蜂群中可能的良性居民外，我们的观察表明 Osmia 可能会使用储存的蜜蜂资源来提供后代。可以想象，常驻蜜蜂甚至可能充当代理人，因为 Osmia 茧是用蜂蜜蜂蜡附着在一起的，似乎在 Osmia 发育过程中存在蜜蜂宿主。除了解决对蜜蜂的潜在新生物威胁外，
