Yellow Feathery Antennae Robber Fly - Ommatius coeraebus
Family Asilidae
This page contains pictures and information about Yellow Feathery Antennae Robber Flies that we found
in the Brisbane area, Queensland, Australia.
- Body length 20mm, male
- Notice this robber fly has the antenna in plumose form, i.e., like a
feather. Its legs are black femur with yellow tibia and black tarsus. Wings
are dark brown in colour.
- Female
- Also notice its "beard" of setae around the face. It is believed that they serve as protection to their face from damage by their prey.
- Male
- They are active predators on flying insects, unselective in prey species. Their long legs can capture other flying insects on flight.
- Male
- Marginal cell on wing is closed. Male of this species have the wings costa vine curved outwards.
