P.irminia. some of them didnt have the white spec and they where also infertile. she dropped 180 inf eggs

all the eggs i ever had with the white spec never developed. like jozua said is true. the dull milky ones are usually fertile.

I sure hope they hatch. I must have a few

From what I've heard and seen is when the white spot is in the center of the egg it will still develop most of the time but when the white spot are on the side of the egg close to the shell they wont develop. When the white spot are in the center the egg will go cloudy as development progresses and eventually the little guy will start to develop inside.

So I was going through some of my emails looking for information and I found these photos of infertile eggs I had from a egg sack.
