One kind of green slug sounds pleasant to the ear, and the other is a large black slug, which is clear and noisy. Slugs themselves don't bark, but the sound they make is the friction of their wings.
The male horn is a round and loud sound made by the rubbing of the front wings of two leaves, which is used to attract the opposite sex, call for the same sex and alarm the enemy.
The anterior wing of male organ is in the posterior region, which is wide at the front and narrow and flat at the back. The back of the front wing is yellow-brown, and the side of the front wing is mostly green with multi-winged veins. The back of the wing is thick and the side of the wing is thin.
Generally, the length of male forelegs is 14- 18mm, and there are a few large wings, the length can reach 20-30 mm, while female forelegs are shorter, generally about 6-8 mm.
The front wing of male insects is generally left wing, that is, the left wing covers the right wing. When singing, the two front wings tilt and rub back and forth, thus making a loud sound. The more developed the wings are (the wings are big and thick), the stronger the friction and the louder the sound.
