Desert Locusts (IMAGE) University of Cambridge Caption A solitary male desert locust (left) faces a gregarious male (right) of the same species. Shown above them are their brains as revealed by computer-assisted microscopy. The solitary locust is slightly larger and has disproportionately large eyes, yet the swarming gregarious locust has the bigger brain. The brains also have very different proportions: in gregarious locusts, the central part of the brain (shown in solid yellow) is disproportionally larger than the optic lobes (shown in translucent yellow), which process the visual information provided by the eyes.
