Oncopsis flavicollis


Length 4.5 to 5.5 mm. Rather variable in appearance so identification can be complex. Male usually with strong dark markings on the face; intraocular band reaches both eyes; discoidal spots present. Female very variable with several colour forms, although the shape of the ovipositor is diagnostic. Nymphs are also very variable in colour and markings.
