Cicadas raging in mid-west America

In May, billions of cicadas will " attack " the Midwestern states, after 17 years hiding under the ground. The red-eyed insect, the body looks like a small shrimp, flies, doesn't bite or inject anything. But their ' choir ' can drown out the sound of the phone ringing, the engine of grass mowers and power tools working.

Cicadas do not harm people, even though they may clumsily touch people. They are delicious dishes for many types of birds, squirrels and especially dogs. Cicadas have a lot of protein. Some say that when grilled, cicadas taste like shrimp. Many peoples in the world still have the habit of eating this insect.

Tom Tiddens, a Chicago Bonatic Garden plant expert, commented: 'The animals will have a good meal, like Thanksgiving for them.'

The latest " attack " occurred in 2004, when cicadas covered many places in 15 eastern states. Daniel Summers, an entomologist at the Field Museum, remarked: 'It is one of the world's most terrifying insect appearances on the surface.'
