Another black aphid mass cluster on the Broad Bean drew my attention. Bending for a closer look -- I was taking photos of the fantastic white flowers with the black markings anyway. A tiny, tiny, tiny trichogramma wasp was busy laying eggs ALL OVER the aphid herd.
I tried to take pictures. I'm not sure if they came out. Am having upload issues (again!) I'll come back and post photos if they're any good.
Letting your some of your lawn grass flower is a GREAT way to attract trichogramma wasps and hoverflies, etc. beneficial insects.
