Apis maxillosa LINNAEUS 1767; Chelostoma culmorum LEPELETIER 1841; Heriades parumcrinitus ALFKEN 1932
A larger version of the more frequently encountered C. campanularum; of the same general long, thin cylindrical shape, but with distinctive white bands of short hairs on the apices of the abdominal segments.The males also have a two-pronged peg on the final segment of the abdomen and this may be used in the same way as that on the males of C. campanularum. However, I have only ever found males curled up around the base of the stamens of buttercups during poor weather, apparently relying on the closure of the petals to shelter them.
More widely distributed than its sister species, being found throughout England and Wales.There are no substantiated records for Scotland or the Channel Islands. It is, however, sporadic in occurrence. Widespread in Europe, and is also found in North Africa.
