About Byturus ochraceus (Scriba, 1790)
Byturus ochraceus is morphologically very similar to other species in the genus Byturus. All species in this genus are unlikely to be confused with species from any other family. Byturus ochraceus individuals measure 4.0–4.6 mm in length, and have a yellow-brown body covered in yellow hairs. The pronotum curves unevenly toward the front, making a front angle clearly visible. The long diameter of the eyes is distinctly greater than half the width of the frons. The underside is colored dark brown to black. By June, some individuals change color to grey-brown. Adult Byturus ochraceus are active from May through July. They are associated with a wide range of host plants, which include Taraxacum officinale, Salix, Caltha palustris, Potentilla anserina, Anthriscus sylvestris, Geum urbanum, Geranium robertianum, Alliaria officinale, Hieracium praealtum, Silene dioica, Stellaria nemorum, Lactuca muralis, and Ranunculus repens.
