Cicadas: The Noisy Insects of Summer

Introduction

Cicadas are a superfamily of insects of the order Hemiptera. They are known for their loud, buzzing song that can be heard throughout the summer. Cicadas are found on every continent except Antarctica, and they are most commonly found in warm, temperate climates.

Physical Characteristics

Cicadas are large insects, ranging in size from 0.5 to 2 inches in length. They have stout bodies, broad heads, clear-membraned wings, and large compound eyes. Cicadas are also characterized by their triangular-formation of three ocelli on the top of their heads and their short, bristle-like antennae.

Life Cycle

Cicadas have a complex life cycle that can span several years. The adults live for only a few weeks, during which time they mate and lay eggs. The eggs hatch into nymphs, which live underground for several years before emerging as adults.

Diet

Cicadas feed on the sap of trees and plants. They insert their long, straw-like mouthparts into the bark of trees and suck out the sap. Cicadas can cause damage to trees by feeding on their sap, but they are not generally considered to be a major pest.

Song

Cicadas are known for their loud, buzzing song. The song is produced by the male cicadas to attract mates. The song can be very loud, and it can be heard for miles around.

Conclusion

Cicadas are a fascinating group of insects that are found throughout the world. They are known for their loud, buzzing song, and they are an important part of the ecosystem. Cicadas can cause damage to trees, but they are not generally considered to be a major pest.
