Starý, J. & Salmela, J. 2004: Redescription and biology of Limonia badia
(Walker) (Diptera: Limoniidae). - Entomol. Fennica 15: 41-47.
Limonia badia (Walker, 1848), previously known from the Nearctic Region only, is redescribed from Finland. Its systematic position and biology are currently debated. Limonia indigenoides (Alexander, 1920), another Nearctic species, is synonymized with L. badia. The species is distinguished by several distinctive characters, such as the wing pattern and the structure of the male terminalia. These characters are illustrated for the first time. Immature stages are probably associated with decaying wood of aspen (Populus tremula L.). A list of species of the Tipuloidea associated with L. badia in Finland – including Gnophomyia acheron Alexander, 1950, a species new to Europe – is presented.
