Interesting about the parasitic wasp

  • Ichneumonidae or Ichneumonidae describe a family of parasitic insects that is one of the hymenopterons.
  • Within the parasitic wasps, a distinction is made between several subfamilies.
  • Cygnet wasps are spread all over the world. Most species are found in Europe, Asia and America.
  • All parasitic wasps share their slender, elongated body. The females also have a laying spike about the same length as their body.
  • Depending on the species, parasitic wasps grow between several millimeters and a few centimeters.
  • With a body length of five centimeters, the Giant Woodland Grebe wasp is considered the largest member of this family. The females of this species are ten centimeters long with sting.
  • Acne wasps are striking not only by their compared to the chest piece almost twice as long abdomen, but also by the long antennae and long front legs.
  • Depending on the species of the parasitic wasp is black, brown or reddish colored. Some species are dotted black-and-white or look very similar to normal wasps with their black and yellow stripes.
  • All parasitic wasps have developed a unique strategy to provide food for their larvae.
  • With their excellent sense of smell, the females detect the larvae of spiders and insects such as bees, wasps, beetles or butterflies, which they inject their eggs with their long laying spike.
  • With the laying spike, they inject a poison into the host larvae before oviposition to numb them.
  • After the parasitic larvae have hatched, they feed on their host and its food reserves.
  • They have the ability to break the cells of the host larvae and to consume them in large quantities.
  • They undergo the metamorphosis to the adult insect in the cocoon or nest of their host larvae. In many species, the larvae also hibernate in the shelter of their hosts.
  • European wasps are found in forest clearings and at forest edges, in meadows and bushy landscapes, as well as in parks and gardens.
  • The adult Imagines feed on nectar, honeydew and bee pollen.
  • The parasitic wasps are a welcome parasite, as their lifestyle contributes significantly to preventing large crop failures caused by insect pests.
  • Some species are selectively bred to reduce the population of pests such as moths or beetles.
