Lacewing Eggs Comparison

I assume these are hatched lacewing eggs, though I think there are other critters that lay stalked eggs as well. What I found interesting was how long the stalks are relative to the eggs. The lacewing eggs I usually find have relatively shorter stalks. Compare the hatched ones above with some unhatched ones below that I found in a park close to home.

Searching around the internet I see two common explanations for why eggs are laid on stalks. First, the stalks make it more difficult for predators such as ants to reach the eggs. The stalks are sometimes even coated with a repellent substance. Second, lacewing larvae are cannibalistic and the stalks serve to keep keep newly hatched larvae away from each other.
