The larva of some species as azuren Fall. {Protocalliphora Hough) 

 is known to attack youngs of birds, as sparrows, swallows and others, 

 in the nest, and generally destroy them; other species no doubt live 

 in carrion and the like. 



Of the genus 4 or 5 European species are known, one occurs 

 in Denmark.
