I was sorry to see a green lacewing floating in a water dish. It did give me a chance to show how small this insect is. The photos show the size, about 3/8" of an inch against a dime. Then with it among the green fly, and how fantastic the wings are. Three eights of an inch is not very big but it's the young that eat the aphids.
They are great insects---they look good and they eat pests. The only thing that I don't like is how they smell. hahaha. Perhaps this is a defence mechanism.
A really lovely and beneficial insect. I just wish we had more of them around here. Sadly (I don't know the reason why) they appear to be in decline in this area.
