There are many species of crickets, but field crickets are common and easy to find. Because field crickets are nocturnal, it is best to collect them at night when they come out from their hiding places near rocks, wet dirt, and grass. Although crickets have wings, they usually prefer to jump. Their powerful legs are their main source of protection. Male crickets “fiddle” more than they fly. They rub their wings together, and the “music” produced by this friction attracts females for mating. Crickets walk with two pairs of front legs, but they jump with a pair of long, rear legs. They have a pair of cerci that function like rear antennae. Each cercus has as many as 720 tiny bristles that detect movement in the air. Once you’ve located a cricket, gently set it on the ground while a partner sets down his or her cricket. Use an area where you can estimate the length and height of the cricket’s jump using a yardstick. Slap your hand on the ground behind the cricket. The cerci will feel the moving air, and the cricket will jump high and away from the danger it perceives. Give each cricket several trials before the cricket no longer reacts to the stimulus, or moving air. Happy jumping! Did You Know? Download 10.24 Kb. Do'stlaringiz bilan baham: |
