The ScatopJiagcK generally prey on other Diptera. " The eggs 

 of 8. stercoraria are deposited in dung, and if not thus sur- 

 rounded with moisture, they shrivel up and come to nothing. 

 But it is equally necessary that they should not be wholly covered ; 

 if they were, the young larva would be suffocated on emerging 

 from the egg. Each egg is provided at its upper end, at which 

 the animal when hatched comes out, with two diverging horns ; 

 these prevent it being stuck more than three-fourths of its length 

 in the dung, in which the female deposits the eggs one by one."
