Yellow-shouldered Hover Fly - Ischiodon scutellaris 

Family Syrphidae

This page contains pictures and information about Yellow-shouldered Hover Flies that we found in the Brisbane area, Queensland, Australia.
Male, body length 10mm
This Hover Fly has the yellow edge on each side of thorax. We sometimes find this Common Hover fly hovering among the hibiscus plants in our backyard searching for aphids.  Their larvae are the predator of aphids.

Some species in tribe Syrphini look very similar. We call all of them Common Hover Flies. They are hard to be distinguished in the field and some of them may not be common. This species is common in Brisbane.

Common Hover Flies may sometimes confused with bees or wasps because of their mimic colour. Their bodies are medium to slender.  On their abdomen there are the yellow-black wasps pattern and the narrow waist mimic pattern. 
Common Hover Flies visit  flowers as bees and wasps.  They are usually seen hovering or resting on flowers. The flies feed on nectar and are the pollinators of plants as well.

Common Hover Fly rests on stick during the evening.

Hover Fly Life Cycle

After mating, female Common Hover Fly look for the good site to lay her eggs. Usually somewhere near the aphids feeding place.

Mating couples                                                                                                                                  
They turn into adults in about a week. The adults are yellow and black in colour look like bees or a wasps. They have the typical fly head with large pair of red compound eyes and short antenna. Adults look for mate and start the new life cycle.  
We found that the Hover Flies could be parasited by Ichneumon Wasp. More information found in the Ichneumon Wasp page.
