Lesions caused by trombiculid mite larvae (‘chiggers’) in birds have been inadequately described. A juvenile red-legged partridge (Alectoris rufa) presented with multifocal, crater-like lesions of necrotizing dermatitis, which often contained multiple orange mites. Microscopically, there was a nodular necrotizing and pyogranulomatous dermatitis with occasional intralesional arthropods. Histologically, the mites were readily identified by the presence of stylostomes within the necrotic areas. Morphological and morphometrical studies on isolated mites identified them as Neoschoengastia (Hypogastia) simonovichi. This is the first report of N. simonovichi as an aetiological agent of severe trombiculosis in wild birds in Western Europe. Infestation with this parasite requires further study to understand its role in animal and human trombiculosis and its potential role as a vector of infectious, including zoonotic, agents.

由 trombiculid 螨幼虫（'恙螨'）在鸟类中引起的病变没有得到充分描述。一只幼年红腿鹧鸪 ( Alectoris rufa ) 出现多灶性、火山口样坏死性皮炎病变，通常含有多个橙色螨虫。显微镜下可见结节性坏死性和脓性肉芽肿性皮炎，偶见病灶内节肢动物。在组织学上，通过坏死区域内茎尖的存在很容易识别螨虫。对孤立螨的形态学和形态计量学研究将它们鉴定为Neoschoengastia (Hypogastia) simonovichi。这是N. simonovichi的第一份报告作为西欧野生鸟类严重血栓形成的病原体。感染这种寄生虫需要进一步研究，以了解其在动物和人类血栓形成中的作用及其作为传染媒介（包括人畜共患病原体）的潜在作用。
