I have some Oriental lilies on which I have been watching for Asian lily leaf beetles and larvae, and killing them when I find them. Looking this morning, I found some white eggs on the underside of one of the lilies’ leaves. Should I kill them now? The Asian lily leaf beetle eggs are supposed to be reddish orange, and I have seen them in the past. These eggs look different (aforementioned color), and are slightly bigger. Thoughts?
Not lily beetles, no; those are not white as you say.
Many eggs laid by insects are beneficial, so I would hesitate to intervene. Look at this great site just to get a sense of how many kinds of eggs there are (and how daunting it would be to ID them, but click on any that look familiar):
