The robin is an insect.

The robin has two pairs of membranous wings, which are essentially the same shape, and a broad, short head with a conspicuously prominent frontal-labial base; it has fairly good eyesight, and the compound eyes are not large, located on either side of the head and are well separated, with three single eyes.

The antennae are short and whisker-like. The mouthparts are elongated, with an esophagus and salivary ducts, and are of the piercing-sucking type. The thorax consists of the prothorax, mesothorax and postthorax, of which the prothorax and mesothorax are longer.

The three thoraxes all have a pair of feet, leg segments are stout and developed (the forelegs are used for digging in the case of wakame, and the leg segments are enlarged and spiny). The abdomen of the cicada is long conical, with 10 abdominal segments in total*** and the 9th abdominal segment becomes the caudal segment.

Expanded Information:

1. The larvae of the robin live in the soil and have a pair of strong excavating forelegs. It utilizes stinging mouthparts to suck sap from plant roots, weakening the tree and causing the branch tips to die, affecting the growth of the tree.

2, when a black crack appears on the back of the robin's nymph, the process of molting begins, the head comes out first, followed by the exposure of the green body and wrinkled wings, stay for a few moments, so that the wings become harder and darker in color, and then begin to take off.

3. At the end of June, the larvae begin to fledge into adults, and the newly fledged cicadas are green in color, with a maximum lifespan of about 60 to 70 days.

4, days in the tree screaming loudly, with a needle prick mouthparts sucking sap, larvae perched in the soil, sucking sap from the roots, harmful to trees.
