Bait,habitat preferences and the phenology of some lesser dung flies (Diptera: Sphaeroceridae) in Britain

Two thousand eight hundred and sixty Sphaeroceridae representing 45 species were caught in eight traps, baited with horse, cow or hamster dung or carrion, placed in woodland and in the open at Silwood Park, Berkshire, during 1983/4. A list of the species and the numbers of each caught in each of the traps is given. Comparisons between the catches of open and woodland habitats and between the catches of the different baits used are made. The habitat and bait preferences and the phenologies of the dominant species are discussed.
