Hoplocampa fulvicornis (Panzer, 1801)

Hoplocampa fulvicornis

The abdomen is entirely black except for the apical one or two segments. The legs are entirely yellow. The first two antennal segments are usually clear yellow, though the remainder of the antennae may be infuscated. The stigma is unicolorous, though some individuals have a marginally darker base. The above features are sufficient to distinguish it from the other Hoplocampa species.
Larvae feed on the fruits of sloes and damsons, etc. Adults will visit other blossoms (pear, apple, etc.).
