Species text
Hylaeus pectoralis is associated with stands of the Common Reed Phragmites australis, in particular the old spindle-shaped galls of the chloropid fly Lipara lucens, which becomes available for use by H. pectoralis after the fly emerges in early summer. The map shown in Else (1995) shows less than 40 10km squares with records of the species, and fewer post 1970 records. It should clearly be considered Nationally Scarce (Notable). In Essex the bee has only been found in a handful of sites, and has only been frequent at Canvey Wick SSSI. References
