Nysius senecionis

Length 4 to 5 mm. N. senecionis has the 2nd antennal segment pale with a dark ring at the base and the wing membrane is usually clear and unmarked. It is separated from the very similar N. graminicola by the shorter 1st segment of the hind tarsus, which is less than the combined length of the 2nd and 3rd segments (including claws). In addition, the matt area of the metapleuron is extensive.

Detailed examination of the specimen is needed to identify the species (a photograph alone is not normally sufficient because key features are too small or hidden).

Nysius is a difficult genus and most of the seven UK species are very difficult to identify without reference to a specimen and use of a microscope.

It is associated with a range of composites such as Ragwort and Fleabane.

Adult: All year.

A fairly recent arrival in Britain, first recorded in 1992 and now widespread and common in much of southern Britain as far north as Yorkshire.

Rarely recorded in Leicestershire and Rutland.
