The silk thread emerges through the worm's lip and is actually hardened saliva. The cocoon spinning process takes about three days. ... Once the silkworm spins its cocoon it starts to pupate - it begins to change into a moth. This process takes around a month, and then the moth will emerge from the cocoon.

What happens in the pupa stage?
The metamorphosis from a caterpillar into a butterfly occurs during the pupa stage. During this stage, the caterpillar's old body dies and a new body forms inside a protective shell known as a chrysalis. Moth caterpillars and many other insect larvae spin silk coverings for the chrysalis.
How pupa is formed?
The pupa can be one of three forms: exarate, with the appendages not attached to the pupal skin; obtect, with the appendages attached to the pupal skin; or coarctate, where the pupa occurs within the shed exoskeleton of the last larval stage.
What does pupa look like?
Moth pupae are usually dark in color and either formed in underground cells, loose in the soil, or their pupa is contained in a protective silk case called a cocoon. ... Pupa, chrysalis, and cocoon are frequently confused, but are quite distinct from each other. The pupa is the stage between the larva and adult stages.
What is the difference between pupa and cocoon?
Cocoon is a structure while pupa is a stage in the lifecycle of insects. Cocoon accompanies the butterfly lifecycle, whereas pupa stages are present in all the holometabolous insects. A cocoon does not become anything after the pupa has escaped while pupa becomes an adult. Pupa is a life form, but not the cocoon.
Which comes first pupa or larva?
The Larval stage emerges as soon as the egg hatches which is the first stage of the lifecycle of an insect. The Pupal stage comes after the Larval stage. The pupal stage is much more sedentary when compared to its larval stage.
What are the stages of incomplete metamorphosis?
The life cycle of insects that undergo incomplete metamorphosis (or hemimetabolous insects) takes place in three stages: egg, nymph and adult.
How do you know when a caterpillar is about to pupate?
When the Monarch caterpillar gets ready to pupate it will spin silk, attach itself and hang head-down in a “J” shape. The caterpillar will stay like this for around 24 hours. Shortly before its final molt the caterpillar will straighten some and the antennae will become ragged rather than the normally rigid appearance.
What are the different types of pupae?
There are two basic kinds of pupae, exarate and obtect. An exarate pupa has free appendages. An obtect pupa has the appendages adhering to the body wall. Most Lepidoptera, most lower Diptera, some chrysomelid and staphylinid beetles, and many chalcidoid Hymenoptera have obtect pupae; nearly all other pupae are exarate.
What is pupa very short answer?
A pupa (Latin: pūpa, "doll"; plural: pūpae) is the life stage of some insects undergoing transformation between immature and mature stages. The pupal stage is found only in holometabolous insects, those that undergo a complete metamorphosis, with four life stages: egg, larva, pupa, and imago.
Do pupae move?
For the most part, pupae don't move. While all these changes take place they stay right where they were formed. For some species that means hanging from a tree, others are tucked under a leaf or buried in soil near the plants they ate as larvae.
What to do if you find a pupa?
If the host plant starts to wither, dislodge the pupa, taking great care not to damage it. It will normally be hanging from the tip. Remove it with a little of the plant still attached. Attach the tip of the chrysalis to a scrap of paper with a minute dab of insect-safe glue.
How do you know if your pupa is alive?
A cocoon from which a butterfly is about to emerge will either turn very dark or become clear. Overly dark cocoons, though, may point to death. Gently bend the abdominal region of the cocoon. If the cocoon bends and stays bent, the caterpillar is probably dead.
What do you know about pupa?
A pupa is an insect that is in the stage of development between a larva and a fully grown adult. It has a protective covering and does not move. The pupae remain dormant in the soil until they emerge as adult moths in the winter.
Is pupa another name for chrysalis?
A pupa is the life stage of insects that undergo a complete metamorphous from embryo, larva, pupa to imago or adult. ... Most are just called pupa but butterfly pupas are called chrysalis, a cocoon is made out of silk that a moth caterpillar spins around itself then pupates inside.
How long do caterpillars take to pupate?
Many caterpillars are fully grown and ready to pupate within a few weeks of hatching from an egg, such as the Painted Lady (Vanessa cardui) butterfly (above left) that only takes 4 weeks.
