迄今为止，只有很少的记录显示寄生螨来自黄蜂。我们发现南方赤蝇幼虫以捕饵器捕获的大黄蜂为食。螨虫似乎更喜欢有花柱的大黄蜂。因为在7年以上的采集中，267V.分析柱头化的工蜂有22只幼虫螨，而297只非柱头化的工蜂没有幼虫。单个寄主上的螨虫数量从1到5不等。螨虫幼虫几乎总是出现在雄虫占据的土体之间的空隙中，而螨虫丰满的身体表明它们确实以宿主为食。我们研究了柱头化通过在大黄蜂的触角之间打开缝隙为螨提供合适的取食场所的可能性。
Parasitic mites have thus far been recorded only rarely from vespine wasps. We found larvae of the erythraeid miteCharletonia southcottifeeding on hornets, mainlyVespa analisworkers that had been collected with bait traps. The mite seemed to prefer hornets stylopized byXenosspp. as hosts to non-stylopized individuals, since in collections made over 7 years, 22 of 267V. analisstylopized workers had larval mites, whereas there were none on 297 non-stylopized workers. The number of mites on a single host varied from one to five. The larval mites nearly always occurred in gapped spaces between tergites occupied by maleXenospuparia, and the mites’ engorged bodies showed that they did in fact feed on the hosts. We investigated the possibility that stylopization provided the mite with a suitable feeding place by opening gaps between the hornets’ tergites.
