Underground structures of the OS

Some species are solitary insects that build shelters for themselves and their offspring, live in the soil. This is due not only the development of certain building instincts, and the appearance of specific morphological structures. In this respect, the remarkable mole cricket. Their front legs turned into a typical digging organs with which insects perform a large amount of excavation. Suffice it to say that the ordinary mole cricket prokativaet underground a network of branched passages at a depth of 10-20 cm in the summer and in the winter deepens to 1 M. With this activity of mole crickets is associated with its Latin name, which translated into Russian language means “cricket-mole”.

Many species of wasps construct few combs. They are often located in tiers one under the other. In this case, the first is based top cells. As more families and expanding the nest to the first cell using the legs is attached the second hundred, etc. the Nesting structure of this type is characteristic of the genera spring, parvispora, polybia, etc. Some intermediate position between single-stage and multistage arrangement of cells is the nesting design of the concentric type, such as, for example, OS nectarine, inhabiting the tropical parts of South America. Honeycombs in the nests of these wasps have an Orb C shaped. The cells are strengthened on the common base constituting the spiral sakrusenergo nests.

Some kinds of wasp nesting is limited only to the construction of a honeycomb reinforced and tuned during the development of the family. Cell not covered by the socket shell of the genera ralistes, belonogaster, INOGATE, etc. parvispora Wasp genera, Vespa, polybia, etc. be erected around a hundred protective shell. Some species of wasps that build nests under the open sky, to strengthen the shell further cover the outer part with various substances. For example, Polybius of rejects — inhabitant of the South American tropics covers the nest with a layer of soil that contributes to its thermal protection. Domed nest shell in OS cliparea weyrauchi covered by a transparent film, which, apparently, the result of secretory activity of the inhabitants of the nest.

Loose wood is a primary building block of the OS.

They grind its jaws into small particles that are mixed with a special secret and turn into a doughy mass. With the help of the mandibles of the wasp nest and honeycomb mold shell. The solidification of this mass is formed boomgaarden substance. All structural elements of the nests, built of bomgaars mass, can be reused for its restructuring and expansion.
