Red Tailed Fleshfly

Like other calyptrate flies, S. haemorrhoidalis undergoes complete metamorphosis through four life stages: egg, larva, pupa, and adult. The complete life cycle takes approximately 23 days under laboratory conditions from 1st instar larvae to adult

Sarcophaga haemorrhoidalis

Red Tailed Flesh Fly

The adults resemble normal house flies but are larger and more robust, ranging from 8 to 14 mm in length.

The larvae are white to slightly yellow in color, and worm-like with a pointed head. Each instar has a pair of strong mandibles for tearing and eating flesh and other food

The red tailed flesh fly is particularly important to forensic entomology as it can be the first, or one of the first, arthropods to arrive at a corpse.

The species is a strong flyer and has the ability to fly in inclement weather when other arthropod species are unable to fly.

The red tailed flesh fly are also used to determine the post-mortem interval in death investigations, and because their development cycle is short, they are the most useful for the first three to four weeks after death.
