title: Chrysomya megacephala (Diptera: Calliphoridae) has reached the continental United States: review of its biology, pest status, and spread around the world.
abstract: Chrysomya megacephala (F.), an Old World calliphorid of considerable public health importance, was first discovered in Brazil in 1977 and is now widely distributed in Latin America. Reports that this species has become established in southern California, and the collection of a specimen in Texas, suggest that C. megacephala may be expanding its range rapidly in North America. The biology and worldwide spread of this pest are reviewed to alert entomologists and public health workers to this growing threat.
