In most species, the larvae feed on algae and organic debris, although some are predatory and can even feed on other mosquitoes.The mosquito can complete its life cycle from egg to adult in as little as 4 days, although most mosquitoes grow from egg to adult in about 2 weeks. Despite being poisonous predators, scorpions are valuable as prey because many are relatively large and quite abundant. Snails can have lungs or gills depending on the species and its habitat.Some marine snails may actually have lungs, and some land snails may have gills. It is any of a group of cellulose-eating insects, whose social system shows remarkable parallels with those of ants and bees, although it has evolved independently. They have two pairs of large wings covered with colored iridescent scales in overlapping rows.

About 90 percent of all flies found in human dwellings are house flies.The adult housefly is dull gray in color with longitudinal lines on the thorax and with dirty, yellowish areas on the abdomen. API call; Human contributions. Check them out;An insect is a creature that belongs to the Hemipteran order of insects, commonly known as true bugs. They are great hitchhikers, easy to transport, and found in many different types of dwellings, making them difficult to control.They do not have lungs, most have compound eyes and are cold-blooded. Without bees, pollination would be difficult and time-consuming: an estimated one-third of the human food supply depends on insect pollination.Bees are also equipped with two wings, two antennas, and three segmented body parts (the head, chest, and abdomen). Adult wasps can feed on nectar and, in some species, on secretions produced by larvae. They take the temperature of their environment.Crickets are omnivores that feed on organic materials, as well as decomposing plant material, fungi, and some seedling plants.Crickets have relatively powerful jaws and are known to bite humans, primarily without breaking the skin.

Snail-shaped animals that do not have a shell are generally called slugs.Most snail species have a tape-shaped tongue called a radula that contains thousands of microscopic teeth. Earthworms generally stay close to the soil surface but are known to tunnel up to 2m deep during dry spells or in winter.Lice are small insects about the size of a sesame seed (2–3 mm long.

Body size ranges from about 5 to 7 mm (0.2 to 0.3 inches), and conspicuous compound eyes have about 4,000 facets. It is any of approximately 1,500 species of elongated arachnids characterized by a segmented curved tail with a poisonous stinger on the back of the body and a pair of gripper forceps on the front.Scorpions are relatively large among terrestrial arthropods, with an average size of approximately 6 cm (2.5 inches).

Their bodies are generally pale and gray, but their color may vary. Lice feed on blood from the scalp but in a small amount. The two forewings are stiff and leathery, and the two long, membranous hind wings are used for flying.Most female crickets insert eggs into the ground or into the stems of plants with their long, slender ovipositors, sometimes causing severe damage to plants. Some species of grasshopper eat toxic plants and they keep toxins in their bodies for protection. They require food before copulating, and copulation is completed in as little as two minutes or up to 15 minutes.The house fly is 5 to 7 mm long, and the female is usually larger than the male.

The most striking physical feature of snails is their spiral shell that they carry on the back.It is a hard structure made of calcium carbonate, which protects their soft body and internal organs. Glowworm often lives in damp and humid areas.Some live in drier environments but are later found in localized areas that retain moisture. The moth spins a silk cocoon that is processed to produce silk fiber. The lower part of the male is yellowish.
