Blow flies are belong to the Family Calliphoridae of flies under Order Diptera. To date, there are around 1,100 species of blowflies worldwide. Blow flies are often metallic in appearance, with feathery hairs on terminal antennal segments. Adult blow flies have sponge-like mouth parts, while the maggots have hook-like mouth parts.
Female blow flies classically lay their eggs on dead meat, where maggots hatch within 6 to 48 hours. These maggots undergo in three stages within three to nine days, after which they leave their food source and pupate in soil. Within 2 to 7 days, the puparium will be complete. Pupae stay inside it for another 10 to 17 days, at which point they emerge as adults.
Blow flies are attracted to fresh meat and are classically the first organisms to come into contact with dead animals. The meat of dead animals is necessary for larval survival and growth. They are also attracted to the plants that give off the smell of rotting meat and as such, are good pollinators.
