Wasps in many people cause fear, because there is always the chance of being bitten.
But not everyone knows that in the world there are many kinds of insects, many of which differ significantly from our usual varieties.For example, ground wasp: what kind of insect and why is it so called?
These insects are a huge group, which includes no less than ten thousand species.Their representatives can be found all over the world, except for Antarctica and the Arctic.In addition, ground the wasp does not occur at high altitudes.
There are small species of these insects, body length not exceeding two millimeters, but can often see these wasps that are longer than five centimeters.This distinguishes them from other types of operating systems, as well as a unique "collar" formed by the rear edge of the pronotum.On its sides strongly stand shoulder bumps that typically do not reach the base of the wings.
From the name you can understand that earthen wasp species refers to the Copa, but there are species that live in the wood of old trees.If you look on their front paws, it is easy to notice a special comb formed dense row of bristles.It is used as an insect shovels.
Almost all of the wasps take care of the offspring (with the exception of Vespula and Dolichovespula), but these species are distinguished, even on their background.
They have reached a high level of skill in building complex nests.They wasps lay paralyzed spider bite, right to the body that lay eggs.The spillover of these larvae are always provided with fresh food and a state of high.
should be noted that each "cell" with future wasps gently closed with a plug, which is often made of the same materials from which the nest was built.However, some types of resin used special types of trees.
Most often earthen wasp hunts on large spiders, caterpillars, flies and beetles, which eat in large quantities.Small species often consume aphids and moths.These species of wasps are characterized by the fact that often elect only certain species as prey.
Some genera of wasps show has very complex behavior, which is something already can compete with the bee.It is about "progressive" type of feeding the larvae.Some members of this distinguished ammofil (Ammophila) and kind Bembiks (Bembix).
wasps nest excavation of this kind is strongly reminiscent of a full beehive.Larvae fed progressively as eating their prey, removing the decaying remains of previous victims.It is doing this several females, which at the same time caring for multiple sockets.
Adults often feed on the nectar of flowers, secretions of aphids and plant juices.In the hot season, they are going to drink some water sources, and some species are used to "rob" the bees, causing the latter to throw off their supply of nectar collected from zobika.
Almost all of them belong to a single species, which are collected in a group only at the time of withdrawal of the offspring.But some earthen wasps (which has a photo in the article) permanently live in colonies, together snatching food and caring for offspring.
