How do wasps spend the winter

There are queen bees, professional bees and drones in the wasp colony. The queen bee is a female bee that is fertilized by mating with a drone after the previous autumn. The drone dies shortly after mating, while the female bee stores sperm in the seminal vesicle.

When the weather gets cold, fertilized females leave their nests to find shelter, such as cracks in the wall and haystacks, to support the group for the winter. The lower the temperature, the denser the population, the higher the temperature, the looser the population. When the temperature is higher than 7℃, the population begins to disintegrate.

The next spring, the surviving female bees went out alone to find a suitable place to nest and lay eggs. The fertilized eggs produced form female bees, and the unfertilized eggs form male bees. With the increase of professional bees, the hive gradually expanded.

Extended data:

The wasp is a completely abnormal animal, and it has to go through four stages in its life: egg, larva, pupa and adult, and the physical form of each stage is different.

The tail of the larva hatched from the egg is still attached to the bottom of the nest, even if the nest is upside down, it will not fall off, and the worker bee will be responsible for feeding it. When it matures, its body will gradually change from crystal clear to bright yellow.

Then seal a thin cocoon on the hole and turn it into a pupa. When it emerges as an adult, it will break out of the cocoon. It only takes two to three weeks from egg to eclosion. Larval stage feeds on other insects, especially caterpillars.

Newt larvae feed on other anesthetized insects, which are stored by their parents in closed nests built by their parents The larvae of other wasp-like insects are fed by adult bees in the nest, and after eating, the larvae often secrete a liquid that adult bees like to eat. At the midgut end of the digestive tract of larvae, the peritrophic membrane forms a closed sac, which is not connected with the excretory orifice.

Excrements are stored in this bag and are free in the body. After pupation, the capsule becomes hard and black, and falls off with molting. Eggs are usually oval, white and smooth, with 65,438+0 eggs in each nest and a silky stalk at the base until the larvae hatch. Therefore, although the mouth of the hive is downward, the larvae in the nest will not fall off the nest.
