(Anoplius nigerrimus)
Anoplius nigerrimus is one of the most common spider wasps, or pompilids, in Europe. They are mostly black and the females are 6-8 mm long while males measure 5-8 mm. This species may be distinguished from the related Anoplius concinnus and Anoplius caviventris by the 20 setae, or hairs, on the forehead rather than 60 or 45.
