Detecting looming motion directly towards the insect is vital to its survival. Looming detection in two insects, flies and locusts is described and contrasted. Pathways using looming detectors to trigger action and their topographical layout in the brain is explored, in relation to facilitating behavioural selection. Similar visual stimuli, such as looming motion are processed by nearby glomeruli in the brain. Insect inspired looming-motion detectors are combined to detect and avoid collision in different scenarios by robots, vehicles and UAVs.
