Myrmus miriformis

Length 6-8 mm (male) 8.5-10 mm (female). In contrast to other Rhopalid bugs, Myrmus miriformis is rather hairless as and adult and is elongate in shape, bearing a superficial resemblance to some of the Mirid grass bugs. Myrmus miriformis males have two colour morphs: a green form (marked with red) and a brown form, while females are always green. The sexes also differ markedly in size; females are larger and more oval. This species usually has very short, rudimentary wings.

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