RE: Monomad: Lacewing's Balloons

I loved every one of these pictures.

And since I didn't know what the bug was, I went to investigate. I think it's a biological controller.

A generalist predator for the control of a wide range of pests including aphids, caterpillars, mealybugs and scale insects. Supplied as adults in packs of 100, or as eggs (which hatch into larvae during transit) in packs of 500 or 2,000.
Also available in a ‘Garden Pack’ containing 500 lacewing eggs, 6 lacewing release boxes and 2 yellow sticky traps.
