Bees' natural enemies, dealing with natural enemies Bees have defensive signals

The natural enemies of bees are people, swallows, bee tigers, and other insectivorous birds, hedgehogs, bullfrogs, toads, geckos, wasps, dragonflies, garden spiders (but it seems that crab spiders are the spiders that are the most threatening to bees, but they do not weave webs), praying mantises, the scientific name of the toad is toad. , bee lice

If the winter is very cold, the green woodpecker will use its powerful beak to peck through the hive and peck at the bees that spend the winter behind closed doors. The hummingbirds in birds of prey are not afraid of stings because of their dense feathers, destroying their hives and pecking at bee eggs and larvae. Some insects are also bee killers, they sting and kill bees. Mud bees are one of them. They look like large wasps, grab the bees and squeeze their abdomen to remove all the nectar, and then leave the bee remnants to their larvae for food. Dragonflies are a terrible carnivorous insect that also treats bees as a delicacy. Spiders open their webs to prey on bees, crab spiders set traps in the corolla to catch bees, and round web spiders "guard the web and wait for bees".

Other animals are interested in the fruits of bee labor, such as hives and honey. Wasps covet honey stored in hives, a butterfly called the hive moth lays eggs in the hive, and caterpillars use the hives of vulnerable colonies to form nets. A dipterodactyl insect known as the "bee lice" parasitizes bees, especially queen bees, and its door forces victims to spit out food. The most frightening is bee spore disease caused by a single-celled organism, aspergillosis caused by fungi, which can paralyze the respiratory system of bees and blind their eyes. Among mammals, bears are honey gourmen.

　The meticulous division of labor, elaborate social behavior and effective holistic functioning of bees make them super-organisms exist in natural ecosystems. They will transmit information such as the orientation and distance of food to their companions in the form of "dance language". Now, scientists have also found that when encountering predators invading, they also have unique defense signals, reminding their companions on the one hand and warning the enemy on the other.
