Lygus pratensis

    Description

    Length 6-7 mm. This genus is one of the most problematic Mirid groups to identify. The five UK species can overlap considerably in colour, markings and size; some specimens cannot be determined. The most reliable identification features concern the fine detail of the corium, and are visible only at high resolution.

     

    Identification is best done from specimen by experts. Where the image has not received expert verification, which is necessary to be certain of accuracy in this species, it is highlighted with a red box. For that reason it is only claimed as likely to be this species.

     

    Habitat

    In the location that our photographs were taken several individuals were observed, all on Common Ragwort.

    When to see it

    Adult: All year.

    UK Status

    Previously scarce and confined to southern heaths, this bug has recently undergone a dramatic range expansion. It is now widespread throughout much of southern Britain and is much commoner than its RDB3 status suggests.

    VC55 Status

    Fairly common in Leicestershire and Rutland.

    Further Information

    The genus Lygus is probably the most difficult of the Miridae.  The most reliable identification feature is the separation of the hairs on the Corium.  See Bernard Nau's article for more information http://www.britishbugs.org.uk/HetNews/Issue%203_Spring%202004_422Kb.pdf
