Dietary and competition effects on life history attributes of Chrysomya megacephala and Lucilia sericata (Diptera: Calliphoridae) in south-west Europe.

The range of the oriental latrine fly (Chrysomya megacephala) is currently expanding. It coexists with another blowfly with a similar ecology, the green bottle fly (Lucilia sericata), one of the most abundant species in carrion during warm months. It is essential to understand the influence of temperature, larval substrate type, and larval competition on the development rates of these necrophagous calliphorids to evaluate the role and the adaptation of C.
