Make oil gourd, cricket and so on. Do you need to bask in the sun to keep warm in cold weather?

In the wild, water hyacinth and cricket are both yin insects and nocturnal. During the day, they hide in dark places and don't go to the sun. If it's an insect that likes singing, keep it in winter, so long as the temperature is enough ~

Of course, some singing insects belong to male insects, and they sing during the day, such as the most common slug of the Newt family, and some wrens and crickets, such as the rhubarb wren. . .
