Blepharotes coriarius, the giant yellow robber fly, is a species of large predatory fly from Australia in the family Asilidae (robber flies). It was described by the German naturalist Christian Rudolph Wilhelm Wiedemann in 1830. [1]
Blepharotes coriarius is one of the largest known robber flies. [2] It can measure up to 48mm in length (including proboscis). [2] Both sexes have orange abdominal tergites, with patches of black setae along the sides of segments 1-5 and mostly white setae along the sides of segments 6 and 7. [3]
The giant yellow robber fly is found in the Australian states of Queensland, New South Wales, Victoria, South Australia and Western Australia. [4]
Adults can be found from December to February. [3] They are usually seen resting on dead plants, with the body aligned vertically and the head pointing upwards. [3] Insect prey are taken in the air after the fly launches itself from a vantage point. [3] Recorded prey items include beetles, bees, wasps and flying ants. [3] Feeding time varies from less than two minutes (for a large ant) up to 17 minutes (for a scarab beetle). [3]
Males of B. coriarius attempt to mate with any member of the same species (whether male or female) that enters their territory, which is usually the area around a dead tree. [3] Intruding males are driven off by this. [3] A few minutes after successful copulation, females begin laying eggs into gaps of dead eucalypts, or into cracks in the ground at the base of such trees. [3] She generally begins oviposition in the top soil, before gradually flying up the tree, depositing more eggs as she goes. [3]
Pupae first emerge from the soil at the beginning of December. [3] The pupal cases are around 35mm long, with reddish brown spines and processes glistening reddish brown to dark brown. [3]
