Fritillaria meleagris is in bloom and so far has had no issues with the lily beetle at all. That's good... but the problem for your question
@DebbieC , is that I haven't observed a single lily beetle this year on anything - possibly it's still too cold as I highly doubt I killed them all last year. So sadly can't draw any conclusions, but will continue to observe them and report back if I see something.
I can speculate that how much the beetle likes them, may very well be related to how much sun the plants get and the temperature when they bloom. The beetles do prefer a sunny, warm spot in spring. So different planting positions and weather could perhaps give different results, even in the same garden.
