The message
from "Franz Heymann" contains
these words:

By the way, if you used "organic" means other than the highly
ineffectual ladybirds to control aphids, you are also killing off
your ladybirds. They will simply die of hunger if there are no
insects around for them.

Is there research that shows they don't simply fly away to find
aphids
elsewhere?

Where "organic means other than the highly ineffectual ladybirds may
also be in use ..........." and so on ad inf.
