“…In Turkey, studies on larvae of water mite are not advanced and only several studies were published (İncekara and Erman 2008, Taşar et al 2012, Zawal et al 2013, Aykut et al 2016, Aykut and Esen 2017). In Turkey only six species of the genus Hydrachna ( H.
conjecta (Koenike, 1895), H.
globosa (De Geer, 1778), H.
leegei (Koenike, 1895), H.
orientalis (Thon, 1905), H.
processifera (Koenike, 1903), and H.
skorikowi (Piersig, 1900)) were previously known (Erman et al 2010). This study contributes to larval morphology of H.
processifera and its parasitization on Dytiscus
marginalis .…”
