Observations by greentreeant12

Hundreds of these pupa were found in a bucket containing rotting vegetation semi-submerged in water. A few maggots with tails were also observed, many at the bottom of the bucket, fully submerged in water. Some pupa were collected and the pictured fly was what emerged a few days later.

This colony was accidentally found inside of a hollow wooden gall (the left of the two in the first image). The gall was about the size of a golf ball and was found attached to to a Lantana canara stem. When the gall was split open, this small colony was revealed (including workers, winged queens, and drones). In the centre of the last image, a larger worker can be seen standing almost on top of a much smaller worker
