Detect. Lock on. Intercept. ̽��ֱ��remarkable hunting ability of the robber fly

̽��ֱ��robber fly Holcocephala is a relatively small fly – at 6mm in length, it is similar in size of the average mosquito. Yet it has the ability to spot and catch prey more than half a metre away in less than half a second – by comparison to its size, this would be the equivalent of a human spotting its prey at the other end of a football pitch. Even if the prey changes direction, the predator is able to adapt mid-air and still catch its prey.

An international team led by researchers from the ̽��ֱ�� of Cambridge was able to capture this activity by tricking the fly into launching itself at a fake prey – in fact, just a small bead on a fishing line. This enabled the team to witness the fly’s remarkable aerial attack strategy. Their findings are published today in the journal Current Biology.

A small fly the size of a grain of rice could be the Top Gun of the fly world, with a remarkable ability to detect and intercept its prey mid-air, changing direction mid-flight if necessary before sweeping round for the kill.
