The effect of season and urbanisation on Calliphoridae (Diptera) diversity in British Columbia, Canada, using baited traps

Abstract Forensic entomology is an important component of criminal investigations, providing information surrounding a death using region-specific data on the local necrophagous community. To understand community within Metro Vancouver region British Columbia, Canada, field study monitored abundance and diversity Calliphoridae (Diptera) over nine-month period in distinct terrestrial environments. Baited bottle traps ( n = 9) were deployed weekly for 12-hour intervals three different Species, sex, gravidity collected specimens determined. Bivariate analyses revealed significant relationships between species, geographic location, month collection, suggesting that species composition influenced by habitat type seasonal shifts temperature. Sex ratios reproductive ranges differed among habitats sampled.
