Life characteristics of wasps: wasps are social insects. There is no nest at ordinary times, and life in the camp is free. When laying eggs, the female bees build a mud house or choose a suitable bamboo tube to lay eggs in it, and store the larvae or spiders of other insects that have been stung after being caught. One room and one egg are sealed separately, and the larvae hatched from the eggs feed on the stored prey.
Generally speaking, when the temperature is 12 ~ 13℃, wasps will sting people, start nesting at 16 ~ 18℃, and overwinter when the temperature drops to 6 ~ 10℃ in autumn. In spring, the temperature is high at noon, and activities are the most frequent. In summer, it is hot at noon, and activities are often suspended. Go back to the nest at night. Have the habit of liking the light. When the wind exceeds level 3, the activity stops. When the relative temperature is 60 ~ 70%, it is most suitable for activities, and it stops going out in rainy days.
