Aneurus laevis
Family: Aradidae

Unlike Aradus species, the wings of Aneurus flatbugs are completely membranous with the exception of the base. A. laevis is distinguished from A. avenius by the position of the spiracles, which are located around the lateral margins of the abdomen rather than on the underside.

This flatbug is found under the bark of various dead trees which are infected by fungi, particularly native deciduous species such as oak.

Although widely distributed across England and parts of Wales, it is not often recorded. Eggs are laid several times a year and all life stages may be found together.
