Common European Greenbottle Fly Lucilia sericata

These brilliant metallic blue-green or golden flies are unmistakable in sunlight, despite being just 10-14mm long. Their larvae revolutionized wound care through maggot therapy, where they clean infected tissue with astonishing effectiveness. Beyond medicine, forensic scientists depend on their arrival patterns and development rates to estimate time of death with remarkable precision. They emerge in spring to mate, beginning a season where these beautiful flies help solve crimes and save lives.
