This is one of the cutest, most adorable insects I've encountered.
Back home in Mexico city (in a time where our mountains actually had trees), these little fellas appeared in rain times. My parents called them "palomitas de san Juan", altho I'm not entirely sure they're the same species. Their spanish name is "crisopa".
Its latin name is Chrysoperla carnea, and is beneficial for gardens because it eats the aphids that plague roses and other plants.
