Blow flies (Diptera: Calliphoridae) were collected from various carrion baits in Orlando, Florida over 2 periods: Jun 2009 to Sep 2009 and Apr 2010 to Oct 2010. In a previous study conducted from 2002 to 2004 the dominant blow fly in Orlando, Florida, was Lucilia coeruleiviridis Macquart (Gruner et al. 2007). This collection documents a shift to Chrysomya megacephala Fabricius, as the most dominant blow fly species found in Orlando, Florida in 2009 to 2010. These field results have potential forensic implications, particularly in the analysis of cold cases.

En un estudio anterior realizado entre el 2002 y 2004, la mosca dominante en Orlando, Florida, era Lucilia coeruleiviridis Macquart (Gruner et al. 2007). Esta colección documenta un cambio a Chrysomya megacephala Fabricius, como la especie de mosca calliforida más dominante encontrada en Orlando, Florida entre 2009 y 2010. Estos resultados de campo tienen implicaciones forenses potenciales, particularmente en el análisis de casos sin resolver.
