yes and yes! the beetles start about mid-May (over wintered?) and 
start laying eggs.  Between beetles and larvae, the plants are 
stripped of leaves.  Interestingly, my red flowered lilies buds are 
left alone, but the lighter ones are eaten.

That's the beast!

I have had minor success with Neem Oil or other horticultural oils. 
The trick is to get every nook and cranny and keep applying it. But
