摘　　要：Ectoparasitism among insects has evolved innumerable times,exploit-ing hosts as varied as arachnids to vertebrates.The most infamous of ec-toparasitic insects are those that live and feed on warm-blooded vertebrates.These parasites can negatively impact the fitness of their hosts by consuming blood,feathers or other external tissues.Few fossils of vertebrate ectoparasites are known[1],limiting direct insights into the historical presence and interactions of these parasites.While it has been suggested that diverse blood-feeding ectoparasites existed in the Jurassic and Cretaceous periods[1],definitive feather-feeding ectoparasitic insects and chelicerates from the Mesozoic are rare[1-3],and this is of particular interest given that many dinosaurs are known to have possessed feathers[4].An enigmatic lineage of wingless insects(Mesophthiridae),preserved adjacent to partially damaged feathers,were initially interpreted as feather-feeding ectopar-asites[5].
