Insects - Flies
Thank you to Jon Richfield who kindly corrected information on this page in December 2014.
Mydidae - Afroleptomydas rufithorax (Wiedemann, 1821). Body length about 35mm. Powerful fliers.
Clegs, also called horseflies or blind flies, though they are very sharp-eyed. Adult females frequently bite humans painfully, though they do not carry disease to any extent. Like mosquito males, male clegs mainly feed on nectar on flowers if thy feed at all. Cleg larvae are maggots that live in damp habitats such as mud on the shores of dams, and they feed on other insects such as the larvae of biting midges. Clegs look very plain and grey, but seen under a good lens, they have beautiful patterns of iridescence on their eyes and beautiful patterns on their wings.
Bee Fly Makes a loud humming noise in flight. Often settles on sand.
Biting midge (Ceratopogonidae) Marsh Fly (Sciomyzidae sepedon)
wing span 12mm,
In the family Tephritidae one of hundreds of species
Stable Fly (Stomoxys calcitrans) A bloodsucker of animals.
Hover fly family Syrphidae. Important as pollinators and in biological control of aphid pests.
Microdon testaceus is a medium sized bee mimic
Robber Flies catch and subdue their prey in flight, often wasps, honey bees and grasshoppers.
Large species of Crane
fly, family Tipulidae; adults of many species do not feed. Larvae of many species feed on roots of
Kelp Fly (Fucellia capensis) About 10mm long grey in colour.
Small headed fly, Philodera fasciata family
Acroceridae. Nectar feeding adults are
Cranefly (Nephrotoma) Shiny black and yellow
body with very long legs. The adults
Wasp-mimicking Robber fly (possibly Pegesimallus species) makes characteristic abdominal contractions just after alighting. Preys on flying insects such as craneflies and bees.
Drone fly adults are important pollinators, feeding on the nectar of many species of non-tubular flowers such as vygies, members of the carrot family such as Queen Anne's lace, and members of the Asteraceae, the daisy family.
Hippo fly (Tabanus biguttatus)
a large wingspan up to 50 mm. This specimen is small and half the adult size. Adults attack large mammals such as hippos as blood suckers. Their larva
feed on insect larva and tadpoles in mud pans.
Greenbottle fly, Phaenicia sericata
very common in summer.
Flesh fly in the family Sarcophagidae.
