Cute!

Unless I miss my guess, what you've imaged here is the "micropyle" of an egg. (That's the little hole where sperm enters. )

I have not looked closely at this type egg before. Interesting texture right around that thing.

Dang if'n I don't learn something new every day. I did not know it was called that, a micropyle

Thanks for the extra knowledge there Rik as I know little about insects, especially their eggs.

Neat Ken. Looks like Rik figured it out again. Check out the top picture on this page:

Hey that is pretty neat! So there are actually eight holes here, appearing as one.

Pretty cool

Thanks Charlie
