Melecta albifrons (solitary bee) garden

The bee Melecta albifrons is a cuckoo bee to look out for in spring, especially if you have a nesting aggregation of the Spring or Hairy-footed Flower Bee Anthophora plumipes. It is a cleptoparasite or cuckoo bee of Anthophora – this means that the bee (female) goes into an Anthophora burrow and lays its egg with the pollen food supply gathered by Anthophora. When the Melecta egg hatches the larva feeds up on the food supply intended for the Anthophora larva, pupates and emerges next year instead of the host. It is found throughout much of southern England, with an apparent bias towards the south-east. There is at least one old record for south Wales. Any records of the host Anthophora bee or the cleptoparasite Melecta bee would be very welcome.

Melecta is a distinctive spring bee, about the same size as Anthophora, with the head and body entirely black in the female except for a pair of lateral patches of white appressed hairs on most of the gastral tergites (top surface of the abdomen) and on the legs. However, in some individuals, these patches are darker, so that these are not so obvious. The male has more white or yellowish white hairs, on the head and thorax.
