A few days before Cheryl's post, I was raking leaves up around our evergreens
that protect the garden from the west and the north winds. I thought I saw
some woodland plants that I hadn't seen before, so I got down and brushed
away the leaves to see better, and to my great surprize I saw hundreds of
lady bugs under the leaves! My garden has always been blessed with many lady
bugs but I never was quite sure why.

(I just *assumed* commercial lady bugs were bred in a cage somewhere.)

Sounds the same as the moss pickers in the forest.

Marcie, maybe the solution is to educate your customers, and sell them
