Dvuhvostka and earwig

Earwigs are representatives of the skin-winged squad. They have an oblong flat body of brown-chestnut color. Larger males, their body length reaches 1.7-2 cm, females differ in smaller size (up to 1.4 cm). However, in nature there are such earwigs, whose body length can be more than 4 cm.

• there is no body pigmentation on the segmented abdomen;
• the insect of the dvuvostok also has no eyes, their role is played by long whiskers, distinguished by high sensitivity.

Habitat dvuhvosti insects are damp wet rooms such as basements, cellars, garages or located in the lowlands of buildings. You can meet arthropods even in the toilet or bathroom, where there is insufficient ventilation. Vilokhvostki can lurk under the baseboards, in the slots behind the sewer and water pipes or in the insulation between the walls. The accumulation of steam and condensate creates favorable conditions for the habitation and distribution of uninvited guests.

Breeding

It is also surprising how dvukhstki breed. The process of fertilization occurs outside the body of arthropods. During the week, the male lays in the soil at least two hundred spermatophores (capsules with spermatozoa), which retain their properties for two days. The female gathers these capsules with its genital opening, after which she lays eggs into the cracks of the soil (up to 50 larvae appear from one bed).Offspring not experiencing metamorphosis bears a great resemblance to adult insects and differs only in smaller sizes.
