Of these, twelve were found in over a quarter, and four (Sphaerophoria scripta, Episyrphus balteatus, Syrphus ribesii and Eristalis tenax), in over half of the forty-nine sites surveyed. In sixteen sites in Merseyside and Lancashire, 135 species of Hemiptera were found, including some new records for the area (Sanderson, 1992). More species and individuals were found in older, grass or shrubdominated sites.
