A very good picture! I have long been interested in this lens.

[Guppy]

The Laowa 25mm F 2.8, 2.5-5X Ultra Macro is a very good lens that is also suitable for full format.
Image scale from 2.5:1 to about 7:1 (with extension rings).

Enclosed is a picture taken with the ZEISS Luminar 25mm at 6:1 showing the fresh eggs from above.
202 images, stack step size 7.5µm, object side image width 3.9mm.

Stink bug eggs are interesting to observe. I have made time lapse movies of nymphs emerging. The hatch is synchronized and most emerge within an hour or so of their siblings. Squash bug eggs are similar.

Bug eggs are good subjects. There is much interesting detail

Thanks for sharing!

Thank you very much for the interesting films, they complement my picture series very well.

The next picture with the Zeiss Luminar 16mm, at 9:1, shows the eggs shortly before hatching.
339 images, stack step size 3.5 µm, object side image width 2.6mm.

Very nice.

Note the little black "pick axes" that are left behind when the nymph exit the egg. They are quite interesting and probably important for breaking out of the egg. Many years ago I tried to image them, but I did not have the greatest equipment for this. I think they could be more accurately described as a stiffener that allows the "wiggle" of the nymph inside the egg to focus fatigue at specific locations along the egg cap border. The "pick ax" is left in the same orientation at each empty egg. Perhaps a bit like the "key" on an old can of SPAM.

The empty egg shells of Palomena prasina.
You can see the can opener.

Respect for the perfect images and the information.

Referring to the excellent shot of the newly hatched nymphs on their egg-cases, I wonder how you got so many shots for your stack without any of them moving?

[Guppy]

Hello Mike

The nymphs react to shock, they remain still.
Between each picture of the stack series, I lightly tapped the surface with tweezers.
In this way they remained calm.

Hello Kurt

thank you very much for your answer. So no movement between taps?

It is our Autumn here in the UK, but I must try this next year.

thanks again, Mike
