As a rule dust mites live not more than 80 days (actually, approximately 30 days). Females lay 1 or 2 eggs per day. Be careful the more humidity in your home the more favourable conditions for mites development are. There are 1,000 mites in one gram of dust.

According to numerous scientists we should blame dust mites for frequent wheezing, itching, asthma and other allergic reactions. Although everything depends on person’s own predisposition. The most annoying point – you will never get rid of them completely, you can only control their rate.

Symptoms of Allergies to Dust Mites:

• watering eyes;
• runny nose;
• constant itching and sneezing;
• difficulties in breathing;
• hay fever …

Things to do:

• wash your sheets and blankets in very hot water and as often as possible, at least every two weeks;
• put all your sleeping belongings into plastic covers after actually sleeping;
• use synthetic fabrics;
• control humidity and temperature levels;
• make cleanings at least two times a week;
• remove carpets, cloth drapes and blinds;
• change air filters regularly;
• use a reliable vacuum;
• ventilate your house;
• air your rooms.

Good luck and take care )))

Appearance

These birds are native to most of North and Central America. Adults are approximately 1 m high and their necks usually outstretched. Herons weigh near 2.5 kg. As a rule, they create an impression of being tall and very thin, everything (wings, bill, legs, and even neck) are very long. What I like the most about herons – their walking and flying (while in flight, the neck is doubled back). There are 5 species of herons, the only one difference is in plumage and size.

Articulation and habitat

Frankly speaking, Blue Herons are not very vocal birds. There is a general set of sounds, for example, telling about danger or approaching the nest, but not more than that. Great Blue Herons nest on islands or in wooded swamps, actually, it is not a whim, it is a kind of protection from mammals and snakes. They can nest both alone or in colonies.

Feeding

The Great Blue Heron feeds in calm freshwater and along seacoasts. Small fish considered to be their main source of food. Sometimes, they also eat shellfish, various rodents, insects, frogs, and even small birds. The fishing techniques are very interesting to view. At the beginning a bird stand motionless, with its neck extended at an angle of about 45 degrees as to the water’s surface. It is incredible to enjoy its eyes and head looking for prey. When it notices a potential meal, the heron moves one leg forward and then immediately its body unbends, and its head dives into the water, so it catches the prey in its bill.

If you really have an intention to see this butterfly with your own eyes, you are welcome to visit New Guinea, it lives only in a few valleys not far from Popondetta (rainforests) and regarded as an endangered species on the IUCN Red List of Threatened Species.

Queen Alexandra’s Birdwing such a strange and honourable name was given after Queen Alexandra, to Europe this butterfly was introduced in 1906.

As a rule, female butterflies are bigger than male ones. But male species are brighter and more colourful. One very interesting peculiarity: caterpillars of these butterflies adore eating te pipevine plant and it is a toxic one, so the butterfly is toxic to predators and they prefer not to touch it.

These butterflies are real wonders of the world, but they are endangered not only because such processes as deforestation and destruction of habitat, there are a lot of butterflies’ collectors and nothing will stop them from getting such a species, although their collecting is prohibited by the law.

The life interval of the butterflies fluctuate from same weeks to same days for some species.

The butterflies are the cold-blooded animals. The temperature of their body depends on the temperature exterior. Particularly on the rays of sun. Very  interestingly what they can not fly if they have the low temperature. That is the reason that they spend in the sun all the time for draw out the energy. Their existence depends on the sunniness.
