Some insects, such as moths, butterflies and wasps, spin cocoons in their larval stage in order to protect the insect during its pupal stage, during which it cannot act to protect itself. If the cocoon is unwrapped, the pupal insect can appear worm-like, but is not a true worm. The four stages of insect life are embryo, larva, pupa and imago
Earthworms are not insects, but large segmented animals of the phylum Annelida which are segmented worms that may live in the ground. (Other types of true worms may live in the water, or as parasites such as tapeworms.) They do not form skeletons at any stage in their lives. They do not ever create cocoons.
Many creatures have been traditionally referred to as worms, adding to the confusion here. Ranging from caterpillars to dragons, 'worm' is as non-specific in layman's language as 'bug', though both have very specific biological definitions. For example, the caterpillar (larva) of the black swallowtail butterfly is commonly called a 'parsley worm'.
By the way, earthworms do not turn into a cocoon. you may be referring to caterpillars. Earthworms only go underground and hope for the best i hope this helps
What else can I help you with?
How many types of earthworms are there?
There are over 4 thousand different types of earthworms. They are hatched from a cocoon, can regrow segments, and they are hermaphrodites.
Can mud turn into earthworms?
No. Earthworm eggs turn into earthworms.
Do earthworms reproduce by laying eggs?
After two earthworms have mated, the clitellum secretes the cocoon which forms a ring around the worm. The worm then backs out of the ring, and as it does so, injects its own eggs and the other worm's sperm into it. As the worm slips out, the ends of the cocoon seal to form a vaguely lemon-shaped incubator or cocoon in which the embryonic worms develop
The cuff like structure in earthworms used in reproduction?
The cuff-like structure in earthworms used in reproduction is known as the clitellum. During mating, the clitellum secretes a mucus that forms a cocoon around the eggs and sperm, eventually developing into a fertilized egg. This cocoon is then deposited in the soil, where the new earthworms will hatch.
How long does a cocoon take to become a caterpiller?
a cocoon cant turn into a caterpiller because a caterpiller turns into a cocoon then turns into a butterfly
How many earthworms are produced from 1 cocoon?
The number varies depending on the species and the conditions at the time of gestation. A very common species, eisenia fetida, usually has around 4 offspring per cocoon.
Why does a caterpillar make a cocoon?
The caterpillar makes a cocoon to complete the metamorphosis and turn in to a moth, butterflies make a chrysalis.
The clitellum functions as part of the system in earthworms.?
The clitellum is a part of the earthworm's reproductive system. It is the part of the worm that makes the egg cocoon.
What animal lives in a cocoon for part of its life?
A caterpilar lives in a cocoon to turn into a buterfly a moth
What organ is responsible for secreting cocoons in the oligochaetes?
The clitellum, a glandular structure found in oligochaetes like earthworms, is responsible for secreting cocoons. This structure produces a mucous substance that hardens into a protective cocoon for the developing eggs.
What organ system does the clitellum?
The clitellum is a special organ associated with the reproductive system of earthworms. It secretes a mucous cocoon that holds the eggs during reproduction.
What is the casing called before the caterpillar turn into a butterfly?
We call it a cocoon.
