Species text
In Falk (1991b) Passaloecus clypealis was known from about a dozen sites in East Anglia and south-east England. It has been recorded from several sites in Essex near the Thames, especially where extensive stands of Phragmites are growing in relatively dry conditions. It is associated with Phragmites beds in fens, and in the ditches and reedbeds of coastal marshes. The species has been recorded in Britain nesting within the empty cigar-galls of the chloropid fly Lipara lucens in Phragmites and in cut, hollow stems of the same plant. References
