Ancistrocerus nigricornis is a solitary fold wasp . The species occurs in the Palearctic , in Europe, in the Middle East , in North Africa and in the Indomalayic zone, east to Sakhalin , Primorye and Japan. The wasps live in moist meadows, in open countryside, occasionally in gardens and other areas where their feeding and preferred nesting sites are found.

Males of Ancistrocerus nigricornis reach a length of 10 mm, females are 9-13 mm in size. The medium-sized solitary wasps are yellow-black in color, with brown hair on the thorax .

The tergites I – IV of the metasoma show yellow bands on the posterior margin (in the similar Ancistrocerus coreanus the bands on tergites III and IV are missing). In the females, the spot between the antenna base and eyes is missing. The following are also colored yellow: On the head four spots on the clypeus (rarely two or all four are missing) and one spot on the forehead and the underside of the antenna flagella , on the trunk section a narrow band, often interrupted in the middle, at the front of the pronotum , two spots each the wing scales and on the side of the mesothorax as well as a bulky band on the rear edge of the sternites II and III of the free abdomen. On the legs, the tips of the fore legs and the rails of all pairs of legs are yellow, the tarsi are mostly brownish.

biology

The species produces a generation annually ( univoltin ). Males occur from June through September, while females have been observed between February and October. After mating, the males die, the females overwinter and reappear in spring. Adult animals feed on sap, honeydew and nectar of various plants, mainly angelica ( Angelica sylvestris ), hogweed ( Heracleum ), blackberries ( Rubus fruticosus ), nightshade family ( Solanaceae ), goldenrod ( Solidago ) and thistles .

Nests are built in spring and early summer. They consist of holes or tubes in wood, mostly in elderberry or berry stalks, with dividers made of clay. The wasps lay an egg in each cell and bring in paralyzed little caterpillars, mostly of Tortricidae . When the larvae hatch, they feed on this prey.
