Now in modern houses it is almost impossible to see crickets. But in country log huts of the 18-19th centuries these insects were constant "residents", quietly squeaking behind the oven and giving thus a cosiness to the house.
Cricket - "a zapechny nightingale"
Quite so called house crickets earlier. Biologically these "singers" treat Orthoptera an insect from family of crickets. Their homeland is the Far East and North Africa. As crickets are thermophilic beings, favourite places of their dwelling with the onset of cold weather are the houses heated by furnaces and also the heated industrial buildings and heating plants. In warm season these insects live on open spaces.
It is curious that the love for heat and also identical culinary addictions make house crickets similar to red domestic cockroaches. If not to peer at these insects, they are even similar externally! However cockroaches are not able to sing and do not say any sounds heard by the person at all. In principle, too it is impossible to call a cricket "singer", he is a violinist. Crickets play "violin", rubbing the sharp party one prewings about a surface of another.
Appearance of a cricket
Crickets – extremely cunning and quick creations. It is very difficult to see them as they very quickly move on the walls, and to catch – especially. However if it is very silent to approach that place from where cricket "trills" reach, in principle, it can and be considered. If carries. Average length of a body of an adult cricket – 2 cm, but meet also individuals up to 2.5 cm long. These insects can have a different coloring of a little body: from straw-pale-yellow color with brown strips to yellowish with motley or mutno brown spots (or specks). As crickets are Orthoptera insects, their wing sheaths in a quiet state have the flat extended form and lie on a back. It is curious what left of them is always covered by right. The head of a cricket is painted with three dark strips. Wings at crickets are perfectly developed and are used for continuous flights from one place on another. Short moustaches (tserka) are available both for a female, and for a male. Crickets lay eggs therefore females possess a long yaytseklad which length varies from 10 to 15 mm. Eggs have length 2.5 mm. In the form they remind ochroleucous banana.
As crickets breed
Males draw with "serenades" attention of females. When couple is formed, there is a fertilization. The female in crevices of the soil postpones until 30 eggs for once. It is curious that crickets, having ended the reproduction, die. In two weeks eggs leave larvae which should winter independently. Growing up, they dig the courses. In the spring of a larva turn into an imago – a full-fledged insect.
