If you have been in villages while climbing trees in the summer season, you would probably have witnessed the nest of small, bee-like animals with usually yellow colored body, called wasps. If so, you might also have been one of the unfortunate victims receiving their stings followed by immediate swelling of the affected body area. Regarding diversity, these organisms form a very diverse group of insects, whereas beetles show even greater diversity. In terms of social behavior, different species of wasps fall into either of the two major categories, namely, solitary wasps and social wasps. Talking of their physical features, they are ectothermic and show bilateral symmetry. Their development from an egg to a fully grown adult involves complete metamorphosis. Sexual dimorphism is also obvious with sexes shaped differently and females larger in size. Considering their lifespan, the majority of the wasps live for less than a year and some die only after a few months.

Wasp Facts & Pictures

Belong to the phylum arthropoda, class insecta, order hymenoptera and suborder hypocrita, a wasp is neither a bee nor an ant. As you look on the wasp pictures, you would see that each individual member has got one pair of wings and three pairs of legs. However, the majority of the members of this group have two pairs of wings. They also have a venomous sting that is present only in females, and is derived from the female sex organ. On their body, you can find either no or a few thickened hair. Looking at their habitat, nearly all the wasps are terrestrial and only a few specialized parasitic groups are aquatic. Here follows a short list of some of the most startling facts about wasps, which besides adding to your knowledge will serve as an instant source of literary and informational entertainment:

  • A single queen, that emerges after hibernation and has dormant sperm cells stored inside her body, is capable of building an entire wasp colony!
  • After building a small nest, the queen rears a starter brood of worker females which then take over the job of expanding the nest while building multiple six-sided cells into which the queen continually lays eggs.
  • Do you know that, by the end of summer, a colony can have as many as 5,000 individuals all of whom, including the founder queen, die off at the beginning of winter, leaving only a few fertilized queens that survive the cold to restart the process in spring?
  • With as many as 100,000 species, wasps make up an enormously diver array of insects but we are most familiar only with those that are wrapped in bright warning colors.
  • The common, familiar species are seen buzzing angrily about in groups and threaten the humans with their painful stings.
  • Are you really aware of the fact that the majority of the wasps are actually solitary, non-stinging varieties?
  • These are the extremely beneficial species of insects to the humans as nearly every pest insect, on the earth, has a predator wasp species that preys upon it either for food or as a host for its parasitic larvae.
  • The features that distinguish wasps from bees include their pointed lower abdomens and a narrow waist, called a petiole, which separates the abdominal region from thorax.
  • Ranging from the familiar yellow to brown, metallic blue and bright red, they come in every color imaginable.
  • Usually, the species with bright body colors belong to the stinging wasp family, called Vespidae.
  • To construct their nests, the bees secrete waxy substance, whereas wasps create their papery abodes from wood fibers which are scraped with the help of their hard mandibles and are chewed to form a pulp.

What do Wasps Eat Is It a Carnivore or a Herbivore?

In mode of nutrition, the wasps depend of different kind of diet during different developmental stages of their life. Owing to their dependence on both animal and plant species, for diet, wasps are herbivores and carnivores, thus more appropriately called as omnivores. In the larval form, they are parasites or parasitoids and become nectar feeders only as adults. The predator wasps use other paralyzed insects for their larvae while, in the parasitic forms, the first meals are derived almost always from the hosts in which the larvae grow. On the other hand, several different types of wasps are also omnivores, thus feeding on a variety of food material, including fallen fruits, nectar and carrion.

How Long Do Wasps Live in Normal Atmosphere

The lifespan of wasps usually depends on a number of different factors. Firstly, health plays a major role in letting them live longer. Temperature also affects their lifespan, as at the beginning of winter the entire wasp colony dies off, leaving only a few fertilized females behind. On average, a wasp does not live for a year and some die even after a few months. However, queens may live for upto a year. It has been observed that at certain point of the year, often around autumn, the bulk of the wasp colony dies away, and only the young mated queens are left alive. The young mated queens that have survived leave the nest and look for a suitable place to hibernate during the winter season.

What Do Wasps Do to Stay Alive During Winter?

Regarding the maintenance of body temperature, different animals fall into either of the two major categories, namely, homeotherms and poikilotherms. The former are the organisms that are capable of maintaining the body temperature against fluctuations in the external environment, while the latter are unable to do so. Wasps are categorized as poikilotherms or ectotherms and do not have a well developed mechanism to keep the body temperature at normal limits against the harsh conditions of the external environment. So, as is the case with other ectothermic animals, when winter season comes, they have to go for hibernation in a suitable warm place. As before the start of winter, the entire wasp colonies dies, leaving only a few fertilized queens behind, the survivors go for long sleep.
