Large Striped Flea Beetle - Phyllotreta nemorum

    Alternative names
    Turnip Flea Beetle or Yellow-striped Flea Beetle

    It has the enlarged hind femora that enable it to jump 'flea-like'. Its black elytra are marked with broad straw yellow longitudinal stripes.  It is very similar to P. undulata  - images in red boxes have not been microscopically examined and can only be said to be representative of P. nemorum.

    Identification difficulty

    It is a pest of brassicas including turnips, the adults feeding mainly on seedlings, leaving them riddled with holes. For this reason it is often found in agricultural fields where brassicas are grown, but also in gardens etc.

    When to see it

    Spring to late autumn when the adults hibernate.

    Life History

    Adults hibernate and emerge in spring to breed and lay their eggs. The larvae tunnel in leaves and become new adults in the autumn.
