Sphecodes albilabris is a large (body length 11-15 mm) solitary parasitic bee that is endemic to Central and Western Europe. It also occurs in North Africa and is thought to have been introduced to the United States and Australia by accident.
This cleptoparasitic species has only recently been found in the UK when it was discovered in Britain in 2020 (Layham, Suffolk). In 2022 S. albilabris was recorded in Oxon, suggesting it is spreading at a fast rate.
Abroad, it is found in association with its host, which is spread widely in continental Europe.
