    TheGreenMan...  With blackfly, it's black, well red-black. 

    With Lily Beetles, it's red, well coccineal. Bigger b*gg*rs than blackfly. It you have to squash the larvae, they are $h*ts!  I pull off the whole leaf and bin.

    I stopped growing philadelphus because of the blackfly.
    I cut Lily beetles in half with pointy nail scissors. Much less messy and they don't get the chance to do the upside down hiding in plain sight thing.

  • I have another Philadelphus which has never had blackfly. 
    I have had them really badly on runner beans in the past.

    Too many this year,found blasting then with the hose, they're back the following day,even the dahlias are badly affected,so it's been a bit of washing up liquid and water in a cheap spray

    Coronarius aureus is then only one I've kept as it doesn't seem bothered by blackfly. I only grow it for the lime green foliage as I don't think the flowers match.

    B3,  perhaps we need a separate thread on Lily Beetle.  Perhaps there aleady is one. 

     But whilst here, would your scissor technique work on a pair caught in flagrante?

    B3:  I doubt thta will be easy.  I'll try to remember , or any of us, to restart a Lily Beetle discussion next season.

    It worked for me. They had their minds in other things
    First snip the humper then snip the humpee.

    I have been using water with a drop of washing up liquid in a spray on both broad and runner beans, to some effect; safer than insecticide.
