Lucilia cuprina
Australian sheep blowfly, bronze bottle fly
Lucilia cuprina, commonly known as the Australian sheep blowfly, is a member of the blow fly family Calliphoridae. It is a significant agricultural pest in sheep-rearing regions, causing the condition known as fly strike or myiasis. The species has been introduced to multiple continents through human commerce and is also utilized in forensic entomology for estimating postmortem intervals. Adults are characterized by their metallic green or greenish-blue abdomen with bronze or coppery reflections.
Melophagus ovinus
Sheep Ked, Sheep Louse Fly, Sheep Tick
Melophagus ovinus, commonly known as the sheep ked, is a wingless, blood-feeding ectoparasite of domestic sheep. Unlike most flies, females produce one offspring at a time through adenotrophic viviparity—larvae develop internally, feeding on secretions from milk glands, and are deposited as fully-formed prepupae that quickly harden into pupae. Populations exhibit strong seasonality, building rapidly in late winter to peak in April–May, then declining through summer. The species has a cosmopolitan distribution wherever sheep are present and is of veterinary significance, though it is not an effective vector for Anaplasma ovis.
