This page contains pictures and information about Acalyptrata flies that
we have founded in the Brisbane area, Queensland, Australia.
The name Acalyptrata refers to lack of calypters in this group of
flies, which is opposite to the Calyptrata
The Acalyptrata is a large group which includes more that
thirty fly families exhibiting very diverse habits. One common characteristic in
this group is there are no known Acalyptrata flies that are obligate
- Family Sepsidae - Ant
- This is a small family. Flies in this family are small and ant-like. They
have the habit of continuously waving the wings when at rest. Adults usually
found in swarm. Their larvae live mainly in mammal faeces.
- Family Lauxaniidae
- The Lauxaniid
Flies has two pair of fronto-orbital bristles. They are usually small to medium
size, with clean or marked wings. They like to rest in shaded forest or
vegetation. Their larvae are usually found on fallen leaves or other rotting plant
- Family Micropezidae - Stilt-legged Flies
- Flies in this family have very long legs, although the front pair is
obviously shorter. Their body is elongated with patterned wings. Most are
medium in size. They
wave their fore legs in front of head when resting on plants.
- Family Agromyzidae - Leaf Miner Fly
- Family Milichiidae and Chloropidae - Freeloader Flies
- Milichiidae and Chloropidae are two very close related Diptera
families. Some species in family Milichiidae and Chloropidae can be found gathering around
feeding spider or some other predator insects in order to feed on their prey.
- Family Platystomatidae - Signal Flies
- Most flies in this family feed on mammalian faeces. Their larvae habits
are varied. Some lives in plant trunk damaged by other insects or fungi. This
group of flies contains the spectacular species, the stalk-eyed signal flies.
The males have eyes on long stalks extending from either side of their
- Family Pyrgotidae - Scarab
- This fly looks similar to those in family PLATYSTOMATIDAE
and TEPHRITIDAE. We determined it is in the
family PYRGOTIDAE by its wing veins patterns (Sc vein reaching the
wing margin at a sharp right angle) and its absent of incurved lower
- Family Tephritidae - Fruit
- Most larvae in this family are fruit feeders and some are serious
economic pests. The female Fruit flies insert their eggs inside fruit and the
larvae live inside.
- Family Ephydridae - Water-skating Flies
- Most species in this family are associated with plants or algae near water.
Drosophilidae - Vinegar
- Vinegar Flies are small in size. They usually have red-eyes and yellowish
body colour. They often attracted to fermenting or rotting fruit. The larvae
are tiny maggots that develop quickly in rotting fruit.
