The male cricket produces his characteristic chirping noises by rubbing his forewings together.  The higher the air temperature, the greater the number of chirps he generates per minute. Thus, you can tell the temperature by counting a cricket's chirp.  Provided that the thermometer reads between forty-five and eighty degrees, count the number of chirps you hear in fifteen seconds.  Then add thirty-seven to this number. The result will tell you the exact air temperature at the time.

Fleas are hard-boiled bloodsucking pests that live in the hair of warm blooded animals, and can pass from one host to another quite easily.  These meddlestone mites do not have wings.  Their mobility depends entirely on their extraordinary leaping ability.  They can jump one hundred times their own height - a feat comparable to a man jumping as high as a forty-story building. Fleas are the insects froming the order Siphonaptera. Fleas are dangerous.  Adult fleas feed on the blood of their  host which they suck after piercing the skin with their specialized mouthparts.  For this reason, several species of fleas can transmit  disease-causing micro-organism from one host to another.
