Odonata wing vein preferences in haemolymph sucking Forcipomyia paludis (Diptera: Ceratopogonidae; Odonata)

In summer 2020, the Odonata fauna in the Weerribben-Wieden National Park was examined at various localities for the Odonata parasite Forcipomyia paludis. This park is currently one of the localities in the Netherlands where the species is found every year. Five localities in the area have been studied and many of the Odonata species were found to be parasitized by biting midges. F. paludis have been studied in more detail on photos of the Odonata species and an accurate overview was obtained on which wing veins they parasitize. The highest numbers of biting midges were observed on the Cubitus vein. Furthermore, 91% of all observed midges were on the lower wing veins of the dragonflies and 9% on the upper ones. Biting midges were not observed in all of the sites surveyed in the park (pdf article).
