Pont (1991) believes that Anthomyia tempestatum Wiedemann , which was recorded by Al-Houty (1989) from Kuwait , is in fact B. tonitrui . In the Middle East it was recorded from Kuwait and Oman ( Pont 1991 ). Biological remarks. The larvae of Brontaea live in mammal dung and sometimes in bird droppings. They hatch in the second instar and are obligate carnivores. Adults of B. tonitrui are attracted by faeces and carrion ( Gregor et al . 2002 ) and they have been reared from human faeces ( Skidmore 1985 ) and also cow dung ( Pont 1991 ).
