Their larvae are predaceous, feeding on the larvae of earlier-arriving flies. Females do not lay their eggs in a corpse until the body is partially decomposed and maggots are available as prey.

Bluebottle blowfly is commonly used as an indicator of the post-mortem interval (PMI). Carrion-breeding blowfly is important forensically because the development times of their larvae are the indicator for determining the minimum time since death.
