I think this is why I have found it hard to let go of my macro lens. In 5 years of hunting, this is only the second time I have come across a robber fly. The first time, I botched up the exposure multiple times with no recourse.
On a photo barren expedition, this was the saving grace. Perched on a leaf, they are ambush predators, catching prey in-flight, stabbing them with their proboscis which is clearly defined in the photograph.
A closer up.
A jittery wasp managed to pose long enough for a clear shot as well.
