This parasitic wasp flew zig zag fashion in front of the post in which many native bees and wasps have nested. Then it would land near a hole and insert its antennae into the hole (bottom photos), before inserting its ovipositor to lay eggs (the 3 top photos).
This very long, slender wasp was laying eggs in the nests of other Hymenoptera. This particular wasp disappeared right inside the nest. Read the photos from the bottom. - First she inserted the ovipositor, gradually disappearing inside the hole. The other two photos were taken as she emerged from the hole.
This small delicate bug (approx. 8mm in body length) was found walking on our kitchen bench. I was confused as to why it didn't have long wings like the Berytidae spp. I had found in the past, but Tony Daley confirmed that it was Berytidae spp. and that some adults seem to have long wings and some short. He said that this specimen is a male.
This young eucalypt tree had been surrounded by a plastic surround (that was put on when the tree was planted). We saw that the area between the trunk of the tree and the plastic had been filled with dirt to about 8" or so up the bag. So we removed the plastic and discovered that the dirt was a bullant nest and they were not happy with the destruction of their home. I took just a few photos, then after five minutes or so went back and got more photos when the bullants were occupied collecting their pupa family members and taking them underground.
