Subfamily Phellinae - Giant Robber Flies

Family Asilidae

This page contains pictures and information about Giant Robber Flies in Subfamily Phellinae that we found in the Brisbane area, Queensland, Australia.
 
 
This is a small subfamily with giant species. Robber Flies in this group are characterized by the possession of a spur vein, directed backward in the first submarginal cell from near the base of the anterior branch of the third vein. They have the wing vein R2+3 open, ending on the wing margin. They have robust and tapering abdomen. Their long wings are broad at the base and tapering gradually to apex. They unusually have wide head and face.

Phellus olgae, body length 45mm, female, male 
This is one of the largest fly species with wing-spans up to 75mm. We saw this fly the first time in Daisy Hill Forest during later summer. It was resting on a large tree trunk. We noticed the fly by its large compound eyes and golden hairs on its face. It flied fast in short distance with loud buzzing sound. Please check this page for more information.
