Barylypa uniguttata (Gravenhorst, 1829)

In comparison to B. propugnator , B. uniguttata is somewhat smaller, with a more sober colouration. Its antennae are shorter in length than the total length of the hind wing. The face is strongly punctured and black, with one yellowish spot centrally. Tegulae yellowish ( PÉNIGOT 2021, in press). The species seems to be less abundant, but this could be partly due to its phenology, being active in early spring (March and April). Especially the males are observed in the field. Its hosts are not yet known.

First report for the Netherlands; confirmed in Belgium.
