Why do bugs start to bark when the weather starts to get cold?

When the weather turns cold, the insects that begin to sing are mostly crickets, commonly known as autumn insects.

There are many kinds of crickets, generally in April-May, the overwintering eggs in the soil hatch into nymphs. The nymph molts 6 times (i.e. 6 instars) for 3-4 days each time, and it takes 20-25 days for * * * to emerge into an adult, and the adult life span is141-151day. The weather turns cold, the adult crickets mature, and in the courtship period, the males begin to sing. Crickets generally start to sing in August, and generally sing best in the wild at 20 degrees, and stop singing in late June when the climate turns cold, 5438+ 10.

Crickets' songs are also quite famous. Different tones and frequencies can express different meanings. Singing has three main purposes:

1. Crickets sing loudly and rhythmically at night, which is not only a warning to other people of the same sex: This is my territory, don't intrude!

2. At the same time, the loud and long-paced chirping of crickets is intended to attract the attention of females, thus winning their favor and gaining the right to mate.

3. When people of the same sex intrude rashly, crickets will chirp in haste as a solemn warning. If the "ultimatum" fails, then a desperate battle to seize territory and defend the leader is inevitable.
