Whose eggs are these? Chrysopidae. See Leucochrysa insularis.
I have seen separated stalked eggs in my yard
that I was confident were lacewing eggs from the photos on this site. But who lays these eggs that have similar size and stalk length but look more oval and are clumped like a bouquet of flowers? A half dozen of these clumps of eggs appeared in areas protected from rain on the glass of a window and on the nearby clapboards of the house. Once I noticed them, no more appeared.
