In insects the egg is too large to allow for the division of the cytoplasm at first. This will occur later as the nuclei get closer to the surface of the egg. For clarity, most of the mitotic cycle has been left out. (microtubules, etc.)

Insects are protostomes as opposed to deuterostomes (sea urchins and humans) and exhibit other characteristics not seen here. See Classification Tree
