I have red lily beetles on my lilies in the back yard and sun garden, though they do no appear to have made their way into the front garden and my six foot tall 'lily trees'.
It looks like these lilies that came with my house will be orange, a colour I am happy with and will fight to preserve.
While the beetle itself is just a beetle and therefore not too disgusting, it lays its eggs in its own excrement which is the disgusting part.
Here you can see them clinging to the underside of the plant and you can see where entire leaves are missing.
Since there are not pesticides that target only the lily beetle and leave the beneficial insects I pick them by hand, the same way I tackled my slug problem in my shady Toronto gardens.
I told you it was disgusting.
