Yes, the mosquitos are swarming 2 at this time of year. Alaska joke the B.Z. the sate 3 bird. But have you ever looked closely the swarm 1 making mosquitos the nuts images? It is a curious thing. The swarm maintains the kind of shape that moves around. But the bugs 4 inside it seem to flirt 5 around randomly 7, rather than flocking like birds. These collective yet disordered flight interest physicists 8 in Rome. They shot auto 9 slow motion videos of swarming images. Then they map the flight of each image, and did the mathematical analyses of the collective behavior. Their finding: the motion of the images is not random 6. The bugs stay far enough apart to avoid knock into a formation. The swarm instead expands as needed to stay just below the reshall? density 10. The work appears on the site Alkida Work? . Flocks and schools move in formation only once the group reaches the critical density. Below that reshall? the individuals move. Well, like images. Insectivores in full-fledged flocks may be a reproductive strategy. After all, it is hard to mingle 11 if you start a line dance.
