Distribution. Hyadina pollinosa is a rare species with scattered records only. It has been recorded from the coast of the Dead Sea in Israel (Mathis & Zatwarnicki 2004a), the Mediterranean Sea with records from Italy (Canzoneri & Meneghini 1987, Canzoneri & Vienna 1988b, 2000, Bertoli et al. 1992, Raffone 2009) France ( Dainat & Dainat 1973, Martinez 2002, this work) and Mallorca (Canzoneri & Vienna 1988a, Canzoneri & Rallo 1996, Ebejer et al. 2006) and along the North Sea coast in Suffolk, and Pool Harbour, Dorset in South England ( Gibbs 2005; pers comm.). Additionally, it has been recorded from few inland salt places in Germany (Oldenberg 1923, Stuke 2023) and from inland places without salt habitats in Slovakia (Zatwarnicki 1996), Fès, Morocco (Vitte 1991), Park HaYarden, Israel (Mathis & Zatwarnicki 2004a), and Volano, Italy ( Canzoneri & Meneghini 1983).

Biology. Hyadina pollinosa is a halophilous species and has been recorded mainly from coastal and inland wetlands that are under the influence of salt water. However, there are records mainly from its southern distribution where it can be found at freshwater wetlands. Adults are recorded from March to October. Dainat & Dainat (1973) reported H. pollinosa to be infested with the Laboulbeniales Stigmatomyces spiralis Thaxter, 1901 .
