Behavior features

Wasp rider

Insect leads an active lifestyle in the daytime, at night, prefers to hide among the grass, leaves, sit on a tree. She tries to stay away from the house because nothing attracts her there.

Imago eats fruit juices, nectar, and some members of the genus do not need replenishment of food supplies at all, but they live no more than 14 days. Riders are called predators because of the need to lay eggs in the body of other insects, arachnids, worms.

On a note!

Wasp rider does not differ aggressive temperament, but the victim feels even under the bark of trees. Often, for searches, he goes into the soil, pulls holes out, as sand, earth wasps do.

Breeding

After mating, the wasp rider begins to reproduce offspring. For our area, the mating season for riders comes in the middle of summer. Until that time, the imago leads a carefree lifestyle, is content with the nectar of flowers, the sap of plants.

For laying eggs a victim is needed - a beetle, a spider, a butterfly, a moth, a larva of large insects. First, the predator tries to bite, then uses the sting.

Breeding wasp rider

According to the parasitizing method, equestrians are divided into several types:

• Ectoparasites. The female lays eggs on the surface of the abdomen, the larvae then gradually penetrate into the body, devour from the inside.
• Endoparasites. The imago thrusts a sting into the body of the victim, immediately lays its eggs. Within a few hours, the larvae appear, which immediately begin to parasitize.
• Superparasites. Oviposition is done both outside of the chitinous coat and inside the body. Special is the fact that they hit their own kind, other parasites.

In the body of one victim can parasitize up to 20 larvae. They actively feed, increase in size. Approximately in 2 weeks they complete their development cycle, leave the victim or what is left of it, pupate. In tropical countries, imago appears during the week, in our area, the wasp rider winters in this state, and in spring an adult individual comes out of the cocoon.

Interesting!

The larvae eat the prey from the inside in a certain sequence. The most important organs are left for last. The victim remains alive for a long time. But at the end of the development of the larvae, only the shell remains from the victim.

The mission of the female is to search for the victim, laying eggs, and later the larvae develop without her participation. Feeding the female provides offspring for the entire development cycle.
