Arge ciliaris - Meadowsweet Fusehorn

Arge ciliaris is one of the black Arge species with a metallic sheen to the thorax and abdomen. It is found locally north to Perthshire (Musgrove, 2022). Hairs on the face and mesopleura are silvery white. The wings are almost entirely hyaline with at most a small black blotch under the stigma. The legs are dark except for pale bases to the hind tibia. Adults will visit hogweed.

Larvae feed only on meadowsweet.
