A study of the dispersal of the sewage‐filter Psychodids requires a knowledge of the breeding haunts and seasonal incidences of the local species of the genus. Field dung, decaying vegetable matter and organic mud form the breeding places to one of which some species confine themselves, whilst others, e.g. Psychoda seuerini Tonn., breed in a variety of materials. P. alternata Say is more restricted in its choice of breeding grounds and proved the best indicator of dispersal from sewage filters. With this fly, invasion of farms and woodland was apparent at a distance of 1/4 and 1 mile respectively from the filters, but not at a distance of 1 1/2 miles in the direction of the prevailing wind.
