Scientific name: Vespa crabro Type: Insects. Key information Hornets appear very similar to common wasps, but are larger and coloured chestnut-brown rather than black and yellow. Hornets have an unwarranted fearsome reputation, but will only sting humans if attacked.
In early spring, every queen will build a new nest. She will not use an old nest, but may build a new nest on the side of an old nest. The storage of sperm inside the female queen allows her to lay eggs without the need to mate again with a male wasp.
Initially, the queen lays approximately eggs. These eggs will develop into sterile females or workers that take care of the colony raising, feeding, cleaning, fixing, defending, and construction. By the end of summer, when the colony is mature and enlarged in size and number, males and new queens are produced in a large number to fly out and mate. Males die soon after mating; while, the newly mated queens seek protected areas for overwintering, and repeat the life cycle.
Usually, social wasp workers live for days, and the average lifespan of queens is about one year. The paper-like nest of social wasps family Vespidae consists of chewed plant material or wood pulp mixed with saliva and arranged in adjacent hexagonal cells.
Unlike the honey bee, wasps do not store food for the winter, and this is why their colonies only last for one season in temperate regions. Wasps will attack honey bee hives in the spring to take away foraging worker bees. Later in the year, wasps will also steal honey and carry off bee larvae and pupae. Chemical stimuli pheromones are used for maintaining the social behaviors and tasks of the colony members. In case of danger, wasps also produce an alarm pheromone to provoke aggressive behavior towards the intruder.
Foraging worker wasps bring raw food that they cannot digest into the nest and pass it to other workers to feed the larvae. In response, the larvae release a creamy drop of predigested materials that contains all necessary ingredients for the workers to eat.
Bees are fuzzy pollen collectors with yellow and black stripes. Wasps are members of the family Vespidae, which includes yellow jackets and hornets.
Wasps generally have two pairs of wings and hairless bodies. Common wasps are paper wasps and yellow jackets Hornets are a large species of wasps and can be extremely aggressive. Hornets are larger and typically brownish and have dull orang stipes on their bodies. Only female wasps and bees have stingers. There are two types of wasps and bees, solitary and social.
