Paropsisterna agricola

The adults of this species can vary somewhat. The common mainland mature form have elytra with golden brown main colouration. In Tasmania the main colourations are grey-green or red-brown with light speckles (particularly bright around the scutellum). An entirely black morph occurs on both the mainland and Tasmania. The teneral (newly emerged) adults of both coloured and black morphs are grey-black with red elytral and pronotal trim that fades as they age, eventually changing to their mature colours.
