Brains of Desert Locusts (IMAGE) University of Cambridge Caption The brain of a solitary desert locust is shown in solid yellow, and the brain of a gregarious locust of the same species in transparent blue at the same magnification. The swarming gregarious locust has a substantially larger central brain. The outermost parts of the flanking optic lobes are, however, wider in the solitary locust, because they serve its larger eyes (which are not visible in this image). Credit Swidbert R.
