Flies that not identified yet


We found quite a number of flies that we cannot identify, not even to family level. Please advise if you recognize any of them.

Unknown Fly 1

? sp. ? family Phoridae, ? Lonchaeidae, body length 2mm

This small fly has the very special feeding habit. They were found only around the Salticid Ant Eater jumping spider when the spider was feeding on ant. We believe the fly feeds on the juice of the ant which was externally digesting by the spider.

Of course this is not welcomed by the spider.

The fly folds the wings flat over abdomen at rest.
