Why do frogs croak less after the rain?

Indeed, after entering March this year, it is really like a rainy solar term. There was a lot of rain, that is, it entered the horrible solar term on March 5, and it was still raining that day. After that, it rained intermittently, and there was fog every day, which was caused by high humidity and low temperature.

March is mid-spring, frogs begin to sing, and Laojiao begins to sing folk songs. Because the worms in the soil have awakened, they shake the dust and stretch after hibernation, but these are what frogs and old pits see, and some worms are destined to be Chinese food for old pits.

But now, because of the heavy rain, it is even frosty and snowy in some places, which leads to the cold weather and low temperature after March. The insects hidden in the soil in winter have not woken up, and frogs and old horns come out late.
