The egg larger; The setup is about 4 to 5 X I think ;)
Cropping has also helped to enlarge the tiny egg.
The egg turned brown.

The egg turned brown.
This is a good thing. Brown is the normal color of a developing egg.

The larva that finally hatches will be nearly black, with some light spots for camouflage.

There is a dramatic shift in coloration when the larvae are half-grown.

I also read that the egg's hatch after 7 days; So that should be next Sunday.
Problem is that we expect rain and wind.

I was thinking to place the egg in a controlled environment (terrarium) but I have no experience in this matter.

I checked the magnification in this setup it is about 3,6 x.

Should be easy to rear to an adult if you place the egg on a living plant (of the same species) in a cage.
Cut off a small piece of stem containing the egg and attach the cut piece to the stem of the plant in a pot. The caterpillar will do the rest!
Best not to touch the egg or the young caterpillar

The egg turned completely black! In fact you can see the carterpilar inside.
A stack from 4 RAW files.
I decided that I leaved the egg outside on the plant. This had consequences the time could not be longer then 1/100 and I had to use the light of the flash.
Lessons for next time, improve the quality of the flash lights. and make an extra plamp to hold a background.

No stack

Interesting to see that there are more insects living on the plant

The probability of it surviving to an adult in the wild is about 1% - that's nature!

The fact that you were able to capture the whole process is just too cool! Very interesting.

Thats true, it could even be that the survival rate was better in captivity.
But I did not had a proper cage, was not prepared as I should be.

day 3 the carterpilar's size is about double;.Estimated 2mm.

This time made with the lumix and olympus 60 macro

Image

and a short video. Shooting in Video you can choose to only use the part used bij the sensor.
That gives a 4k video cropped without quality loss.

Nice image.

This looks like the resting state between larval stages, where the caterpillar has grown as large as it can inside its current skin, and is taking a break from eating to grow a new skin and a new head capsule, inside the old skin and head.

Soon it will split the skin in the front, the old head capsule will fall off, and the caterpillar will crawl forward out of the old skin, leaving it crumpled like a discarded sock.

The new skin will be much larger, so that instead of the "stuffed sausage" appearance shown in this picture, the caterpillar will again appear wrinkled and accordion pleated, like in your first picture.

Barring predation, parasitism, or disease, this process will repeat several times until the caterpillar is full grown and molts one last time to become the immobile pupa.

Under protected conditions most of the caterpillars make it through all these complicated steps, but in the wild their chances are very slim.

Not a good video but interesting behavior!
