A new study on three species of blow flies that commonly factor into forensic entomology investigations examined what drives the timing of their arrival and how they interact. To study those interactions, researchers placed multiple ratios of the different species of blow fly maggots in containers (pictured here) with a mouse corpse on which to feed, and the containers were then placed in a temperature-regulating growth chamber.
