Hence, deficiency of iodine can retard the growth of a larva to become an adult frog. Frogs need to live in water bodies where sufficient iodine is present for thyroxine production. Why does metamorphism occur in frogs and insects?įor the production of thyroxine, thyroid gland needs iodine. If we consider the life cycle of a frog, there are three stages. At last stage, a moth develops from the cocoon. Eventually, it becomes a silkworm and later becomes a cocoon. An adult silk moth starts its life from an egg. The life cycle of frogs and insects involve sequential stages of change. How is the life cycle of a frog different from an insect? The changes in the stages from a larva to an adult are known as metamorphism. These drastic changes in appearance and stages are not as long as human growth. Eggs of a frog develop into a larva (tadpole) and later become an adult frog. The moth is important because it makes silk….Silkworm. ![]() Silk has been made for at least 5000 years in China. The silkworm is the larva( the active immature form of an insect)or caterpillar of the Bombyx mori moth. The entire process can be controlled by keeping the worms in a controlled environment protecting them from ants, mice, and disease and feeding them mulberry leaves. The larvae of silk moth are called caterpillars or silkworms. ![]() (1) The female silk moth lays eggs on the leaves of a tree (such as mulberry tree) (2) The eggs hatch to form worm-like larvae. The larva (or caterpillar) of a silk moth which produces silk is called silkworm. ›Bombyx mori Linnaeus, 1758 ›domestic silkworm ›silkworm The larval stage lasts for about 27 days and the silkworm goes through five growth stages called instars, during this time. The larva of Bombyx mori, commonly called a silkworm, is host specific to mulberry. The larva is the vegetative stage where growth takes place. Several caterpillars form a protective layer around pupa and this covering is known as the cocoon. In the pupa stage, a weave is netted around by the silkworm to hold itself. The silkworms feed on mulberry leaves and give rise to pupa. The caterpillar or larvae are hatched from the eggs of the silk moth. soobee72pl and 20 more users found this answer helpful.Īs nouns the difference between silkworm and silkmoth is that silkworm is any of various caterpillars of moths that produce silk cocoons, especially bombyx mori, the source of most commercial silk while silkmoth is any moth whose caterpillar stage is a silkworm. A silkworm’s preferred food is white mulberry leaves, though they may eat other mulberry species and even Osage orange. It is an economically important insect, being a primary producer of silk. Bombyx moriĪnswer: The silkworm is the larva or caterpillar of a silk moth. It is an economically important insect, being a primary producer of silk…. The silkworm is the larva or caterpillar of a silk moth. If allowed to develop from pupa, and not destroyed at this stage in the cycle so that silk can be created, the caterpillar will develop into a creamy white moth patterned in brown-scientifically named Bombyx mori. The silkworm is actually the larvae, or caterpillar stage, in the life cycle of the silkworm moth. 7 Why does metamorphism occur in frogs and insects?.6 When does a frog develop into an adult?.4 What are the other names of silk moth?.
