Giant Yellow Robber Fly is quite common in Brisbane Eucalypt forests. The only problem is to take their photos and confirm the seeing. During summer season, almost every time when we were in the middle of a Eucalypt forest, we saw this fly. Actually it was the fly who found us and not we found it. Every time of the encounter, we heard a loud buzzing noise then we saw this fly flied pass and rested about two to three meters away.
