Eupteryx decemnotata

    Description

    Length 2 to 3 mm. Without microscopic examination, the vertex pattern is the best identification feature, consisting of three pairs of dark marks, although these are variably fused in some forms. This species is also noticeably smaller than E. melissae.

    Identification difficulty
    Recording advice

    This species can be identified from good quality photographs with care but there are similar species that it could be confused with.

    Habitat

    On the continent this species uses several foodplants, but in the UK it has been mainly found on sage, and thus requires careful separation from the commoner E. melissae.
