Under this name are known several species of the family Scarabaeidae. The most important species in Central and Eastern Europe are the beetle and beetle forest.
Beetles are spread across most of Europe. They can be found on various hardwoods such as maple, oak, beech, birch, mountain ash, poplar, walnut, chestnut, fruit trees and conifers, such as larch and duglas green.
In addition, beetles attacking and various herbs, cucumbers, beets and salad.
Adult beetles feed on the leaves host. If a mass invasion, the tree can be completely leafless.
Generally eaten leaves of plants are replaced by new ones in June.
But the fact that the beetle larvae feed on the roots of the plants can be so bad that the plants become very weak and a stronger storm can be uprooted.
It has a length of 20-30 mm long; head, neck and the back of the armor body and the lower part are black; wings (bandannas) are brown and has some longitudinal elevation, well formed.
The head is inserted a folded pair of antennas that males present to end seven long fringe, like leaflet; Females have only 6 fringed antennae similar, but slightly shorter; larvae up to 65 mm in length; are pale yellow and rounded in the abdominal area (the specific form of the beetle larvae); they have three pairs of legs which start from the chest, and their head is brown and clearly separated from the rest of the body.
Natural predators of beetles are bats, owls, crows, sparrows, blackbirds, hedgehogs, moles, chitcanii, parasitic wasps, flies in the family Tachinidae etc. The soil should be loose and well watered regularly. Layers of plants to be covered with a piece of plastic or canvas stretched on throughout the Flight of the Bumblebee.
To plant dandelions because they are preferred as food beetles. If they have enough dandelions to feed, when other plants are ignored. If using garlic broth, beetles can be expelled.
Beetle flight period is in April and May, and when they swarm in flight at noon and in the evening. After a period of feeding the female beetle lay about 10-30 eggs round and yellow, arranged in piles at 5-25 cm depth in the ground.
Then the female flies again in the forest, fruit orchards or gardens to feed. After this phase feeding her deposit is another round of eggs, but in smaller numbers than before. It lay about 20 eggs at this stage. After feeding a third phase, the third row of the female lays eggs, and lower amounts.
After 4-6 weeks evolution embryonic ends and the larvae hatch. They need 3-5 years to achieve transformation into pupa and then metamorphose into adult beetles.
The larvae feed on the substances Humo and yams. In the last stage of larva transformation into pupa takes place in summer and hatch young beetle already in late summer. The first wintering, then, next spring out of the ground.
And similar related species of the family Scarabaeidae: beetle marbled garden beetle, June beetle and beetle gold.
