“…The other louse fly species identified in this study as Ornithomya avicularia , O. fringillina , O. biloba , O. chloropus and Ornithoica turdi have all been previously reported in Hungary [ 22 ]. The euryxenous natures of O. avicularia , O. turdi and O. fringillina have long been known, as has the host specificity of O. biloba towards the Hirundinidae family (especially the Barn Swallow) [ 10 , 13 , 16 , 22 , 36 , 37 ].…”

“…Hippoboscids were also caught from the environment of the bird-ringing facilities. As many flies can fall off or escape from the bird during the capturing and the ringing procedure [ 10 ], some avian louse flies were found in and around the buildings where the birds were ringed. In these cases, it was impossible to identify the original hosts and, therefore, the term “environment” was used.…”

“…Although studies on louse flies originating from Central [ 3 ] Northern [ 14 ], Southern [ 10 ], Western [ 15 ] and Eastern Europe [ 16 ] have also been conducted, only a few of these report long-term evaluations with continuous sample collection. The number of studies conducted on avian ectoparasites steadily increased in Hungary and in other Central European countries during the previous decade [ 2 , 3 , 12 , 17 , 18 ], but studies on ornithophilic hippoboscids appear to have been neglected compared to other arthropod vectors that are generally considered epidemiologically more important (i.e.…”
Background
Louse flies (Diptera, Hippoboscidae) are important blood-sucking parasites of birds and mammals with a worldwide distribution. The aim of our study was to collect louse flies from birds across multiple sites in Hungary and evaluate the effects of avian traits on louse fly–host relationships.
Methods
Between 2015 and 2022, 237 louse flies were collected from birds at multiple locations in Hungary. The louse flies were identified to species level by morphological and molecular methods. Louse fly species and their seasonal dynamics were analyzed.
Results
Six louse fly species were identified: Ornithomya avicularia, Ornithomya fringillina, Ornithomya biloba, Ornithomya chloropus, Ornithoica turdi and Ornithoctona laticornis. Results of statistical analyses indicated that habitat, migration habits and the feeding places of birds have significant effects on their possible role as hosts of O. avicularia, O. fringillina and O. turdi. Analysis of the temporal distribution of avian louse flies showed different seasonal patterns according to species. Phylogenetic analyses highlighted that O. turdi clustered separately from other members of the subfamily Ornithomyinae which thus did not form a monophyletic group.
Conclusions
This study presents one of the longest continuous collections of ornithophilic louse fly species in Europe so far. Avian traits were shown to influence louse-fly infestation. To our best knowledge, this is the first report on O. laticornis in Europe. The ability of this African louse fly species to survive in Europe, as demonstrated in the present study, may be an indication of its future establishment. Our findings, in accordance with previous reports, also indicated that the subfamily Ornithomyinae should be taxonomically revised.

Graphical Abstract
We present a summarization of an overview of hippoboscid flies parasitizing bird hosts in Slovakia. Six new host associations are presented in this paper: Lipoptena fortisetosa Maa, 1965 collected on Certhia familiaris Linnaeus, 1758 and Sylvia atricapilla (Linnaeus, 1758), Ornithomya biloba Dufour, 1827 collected on S. atricapilla, Ornithomya chloropus (Bergroth, 1901) collected on Anthus trivialis (Linnaeus, 1758), and Ornithomya fringillina Curtis, 1836 collected on Phylloscopus collybita (Vieillot, 1817) and A. trivialis are recorded for the first time from Slovakia.
The checklist of louse flies or keds from the family Hippoboscidae in Romania with 14 species is given. Among them, six species have been newly recorded from Romania, from Natura 2000 site “Dunele Marine de la Agigea” Natural Reserve; namely: Icosta minor (Bigot in Thomson, 1858), Ornithoica turdi (Olivier in Latreille, 1812), Ornithomya chloropus Bergroth, 1901, Ornithomya fringillina Curtis, 1836, Ornithophila gestroi (Rondani, 1878), and Ornithophila metallica (Schiner, 1864). Out of the total, seven species are autochthonous, while the other seven are probably non-native species, either spreading invasively or only occasionally being imported to Romania or migrating to the country along with their hosts. Three new host-parasite associations have been reported for the first time. Specifically, the eastern olivaceous warbler Iduna pallida (Hemprich et Ehrenberg, 1833) represents new host species for I. minor and O. turdi, while the willow warbler Phylloscopus trochilus (Linnaeus, 1758) represents a new host species for O. gestroi.
