Pests to native stingless bee colonies!
About half the size of a stingless bee and they move very quickly, jumping around inside the hive box. The stingless bees do seem to chase the flies but the flies are too fast to be caught. The flies will run around the inside the colony laying eggs everywhere which are tiny little white things as shown in the photos below. You may not even notice them normally.
Removing some eggs for observation
I removed a few eggs from the colony and placed them in to a small area to observe them. You can see how small the eggs are with one being beside the pick tool.
I made a small observation box for capturing and viewing pests from egg to adult.
