Neomyia cornicina

    Alt Name
    Orthellia cornicina
    Description

    There are several lookalike Greenbottle species that occur in different fly families and to the inexpert eye can look confusingly similar. This species has metallic green jowls. The body coloration tends to bronze with age. We are grateful for expert help with identification.

    Similar Species

    The two Neomyia species are separated by the arrangement of bristles on the scutum. N. cornicina has 1 pair of presutural acrostichals and 3 pairs of postsutural dorsocentrals. N. viridescens is without presutural acrostichals and usually has 4 pairs of postsutural dorsocentrals though it can occasionally have only 3 on one or even both sides. (See the labelled photo below.)
