Description
Female

Gymnosoma nudifrons can reach a length of 5–7.5 millimetres (0.20–0.30 in).[5] These parasitic flies have a black thorax and a spherical yellowish-red abdomen with reduced bristles and black markings, often large and triangle-shaped, sometimes touching. On the inner side of the eyes there are black stripes. The males of this species have yellowish dusting on the first part of the thorax. This species is very similar to Gymnosoma rotundatum.[6][7][8]

Adults can be found from May to September. They feed on nectar and pollen of various flowers, especially of Angelica sylvestris, Tripleurospermum inodorum and Anthriscus species. Larvae feed on Pentatomidae.[5]
