New records of calyptrate dipterans (Fanniidae, Muscidae and Sarcophagidae) associated with the decomposition of domestic pigs in Brazil.
Predicting calyptrate fly populations from the weather and probable consequences of climate change.
It has variously been placed in the Calyptratae (Pont 1980: 713); or as a possible transitional family between acalyptrate and calyptrate flies, and probably closest to the Scathophagidae (as Cordyluridae) (van Emden 1950); or as related to families of acalyptrate flies, including Sphaeroceridae (as Borboridae) (Austen 1936) and Heleomyzidae (Sphaeroceroidea) (McAlpine 1989: 1484).
The aim of the present contribution is to investigate the duration of the decomposition stages, as well as the frequency and abundance of calyptrate flies (Calliphoridae, Muscidae and Sarcophagidae) associated with a carbonized carcass, compared with those obtained for a corpse that has not been carbonized.
