Skipper eggs are much different from the highly sculptured butterfly eggs that we usually see in the forums. Their shape is just a smooth rounded cone, with a very subtle surface texture that is reminiscent of "crinkle coat" paint.
Here is the entire egg, attached to the bit of dry grass that mommy skipper glued it to. 4X NA 0.10 objective, focus stacked at 50 µm, cropped. The irregularity at upper right of the egg almost looks like a "transparent foreground" stacking artifact, but it's not. The egg really does have a hard irregular profile at that spot. I have no idea why; I suspect it's an individual defect but I don't even know that for sure.

A closer view, 20X NA 0.40, focus stacked at 5 µm, cropped.

Here's what the egg looked like in situ, after being returned to the lawn. The fibrous plate at upper left is a small piece of masking tape that I used to hold the bit of dry grass to a microscope slide for the earlier pictures. Shot at 1:1 with a macro lens, slightly cropped.

It was surprisingly difficult to get good lighting for the microscope shots. What I ended up with was a single fiber bundle with a Kleenex tissue wrapped tightly around its tip, making a slightly diffused light source of 6 mm diameter, positioned 20 mm away from subject.
Hope you find this interesting!
