Hi.

What insects will eat greenfly (without then becoming pests
themselves)?
I know about ladybirds, but are there any others?

How do I either encourage ladybirds into my garden or breed them
myself? Ditto any other useful insects.

TIA, Jeff

It has been my experience that ladybirds are completely ineffective in
greenfly control.
The problem is that I have never ever seen a plethora of ladybirds anywhere,
so when you look at a preponderance of greenfly on plants and the zero
effect the efforts of half a dozen ladybirds I can assure you that the
statement is a myth. In fact, I have observed ladybirds at "work" resting
on an infested leaf but I have never seen a ladybird scoff a greenfly. I
have never seen more than half a dozen at any one time. Can it be that
persons other than I have seen swarms of them?. I certainly have seen
swarms of green and blackfly many times. I most certainly have seen mnay
times swarms of ants collecting greenfly and toting them down the stems to
their storage underground crypts where they use them as milch cows.
