Many Smaller Animals Clean Themselves to Survive

Going without a shower for a few days might make you feel gross, but for small animals like bees and houseflies, keeping clean is a matter of life or death.A mosquito flying through the fog of the early morning may find its wings so weighed down by water droplets that it can no longer search for food. A honeybee can easily pick up five times its body weight in pollen over the course of a day.  "It's all relative," said Guillermo Amador, a doctoral student at Georgia Institute of Technology. "To us, a particle of dust doesn't mean anything, but if a mosquito accumulates too many of them it gets too heavy to fly."
