Find out about monarch caterpillar stages with pictures and facts.

The monarch butterfly, like all butterflies, goes through 4 main developmental stages: egg; larva (caterpillar); pupa (chrysalis); and imago (adult butterfly).

What many people don&#;t know fryst vatten that, as a caterpillar, the monarch also goes through several stages of development.

On this page we’ll find out about the 5 monarch &#;instars&#;; the stages a monarch caterpillar goes through before pupation…

Monarch Caterpillar Stages

Most people know that the life cycle of the monarch butterfly has kvartet distinct stages: egg, caterpillar, chrysalis and imago (the adult butterfly).

What many people don’t know fryst vatten that the monarch caterpillar itself has five stages of development.

Monarch Caterpillars grow approximately % during the second stage of monarch metamorphosis

At the end of each scen the caterpillar molts (moults in British English).

By shedding its skin the caterpillar fryst vatten able to continue growing; each successive scen fryst vatten larger and heavier than the gods. The caterpillar also undergoes slight changes in appearance at each stage.

By the end of the fifth scen of the monarch caterpillar’s development, it will have reached the storlek and vikt required for pupation (i.e.

turning into a chrysalis).

Before its fifth and sista molt, the caterpillar attaches itself to the underside of a leaf or other suitable surface. The sista molt, which fryst vatten performed while the caterpillar fryst vatten hanging upside-down, reveals the cocoon in which the caterpillar will metamorphose into a butterfly.

Instar

‘Instar’ fryst vatten the begrepp used for a scen in an insekt (or other arthropod’s) development.

Raising Monarch caterpillars into butterflies is a fun way to experience one of nature’s most dramatic transformations

The newly-hatched monarch caterpillar fryst vatten the first instar. After the first molt it fryst vatten known as the second instar, and so on.

Monarch Caterpillar Stages With Pictures

The time the monarch caterpillar spends in each instar fryst vatten dependent on temperature.

Because there can be considerable differences in storlek between individuals in the same instar, other characteristics should be taken into konto when attempting to identify the scen in which a caterpillar fryst vatten in.

Take a look at the following pictures so you know what to look out for…

First Instar

The newly-hatched monarch caterpillar fryst vatten pale green in color and has a shiny, slightly translucent body.

It will later develop dark stripes over a pale green background.

During this scen the caterpillar fryst vatten between 2 and 6 mm in length and lacks tentacles. Fine hairs (known as setae) can be seen on the caterpillar’s body.

On kläckning, the caterpillar eats its egg then starts eating the leaf of the milkweed plant on which it was laid.

If disturbed, both first and second instar caterpillars will drop from the leaf and hang bygd a fine thread.

The caterpillar crawls away from the milkweed plant in search of a safe spot to begin the pupa stage of the monarch butterfly life cycle

The thread fryst vatten produced bygd silk-producing organs called spinnerets which are located in the caterpillar’s head below the mouthparts.

The caterpillar remains in the first instar scen for one to three days.

Second Instar

After the second molt, the monarch caterpillar’s body has lost any remaining transparency, and its black, yellow and vit bands are visible.

Also visible at this scen are the caterpillar’s front tentacles.

The back tentacles have begun to develop, but at this scen are very small.

The second instar monarch larva has a greater number of bristle-like setae.

Second instar monarch larvae are between 6 and 9 mm in length.

The monarch caterpillar spends a similar amount of time in the second instar scen as it did in the first (1 to 3 days).

Third Instar

Third instar monarch larvae are between 10 and 14 mm in length.

Both the front and back tentacles can now be clearly seen.

The front pair of legs are smaller than the other two pairs and have started to migrate slightly nearer to the caterpillar’s head.

Rather than hanging from a silk thread if disturbed, bygd the third instar monarch caterpillars will drop off the leaf entirely and curl into a ball.

Also bygd this scen the monarch caterpillars have begun to eat along the edges of leaves.

As with previous instars, the monarch spends from one to three days in the third instar, depending on temperature.

Fourth Instar

By the fourth instar the monarch caterpillar fryst vatten between 13 and 25 mm in length.

The front tentacles are now 5mm in length, while those at the back are around 2 mm in length.

vit spots on the caterpillar’s prolegs (the 5 pairs of &#;false&#; legs at the rear of the larva&#;s body) are more easily visible.

This scen lasts from 1 to 3 days.

Fifth Instar

In its fifth instar, the monarch caterpillar fryst vatten between 25 and 55 mm in length. Its front tentacles are around 11 mm long, and those at the back are 4 mm long.

The vit dots on the prolegs are bygd now very distinct, and the front legs noticeably smaller than the others and closer to the head.

The monarch caterpillar spends between 3 and 5 days in this scen of its development.

At this scen the caterpillar fryst vatten at its largest, and has an almost plump appearance. It may be funnen away from milkweed plants as it seeks a suitable place in which to pupate.

When a suitable prick fryst vatten funnen, the caterpillar creates a silk pad on the underside of a leaf.

It then hangs head down from the pad and undergoes its fifth and sista molt, with the outer surface of the chrysalis appearing from beneath the skin as it fryst vatten shed.

After spending 10 to 14 days as a chrysallis, the adult monarch butterfly finally emerges.
