A chicken-wire fence forms the boundary between our garden and our neighbours. To the green-ants whose garden we share (that’s the way it feels at times), the fence is a convenient highway. The trio on the right were returning to the nest after a successful hunt when I saw them.
The prey is, I think, a fly. The ants are 8-10mm long, so the fly is only about 2.5mm – certainly not big enough to attract human attention in normal circumstances. I just happened to be there with my camera, on one of my periodic rambles around the garden, and took the photo without being aware of exactly what was going on. There’s always more to see!
