Lily beetles like frits. Look for orange egg clusters on the undersides of the leaves which can easily be scraped off, bright red rectangular adults which are easy to catch and squash. The larvae are disgusting because they pile their own excrement on their backs. I use a twig to knock them into a bowl of soapy water. Prompt action can usually get them under control. Fortunately they are easy to find.

I got the dang rabbit munching on my species type tulips out front right next to the walk where the dogs can't get to, so I feel for you!
I wonder if it is because F. glauca is native to the US so the insect recognizes it as something to eat it? I don't know much about insects: )

Remy, you may well be right about native bugs liking native plants. I don't live that far from F. glauca's native range.

I'm so excited! Why is it that you can look one day and see nothing, and then one day you look, and something has sprung WAY out of the dirt and you must have been blind to have missed it?!

One of my frits popped out when I wasn't looking and is a good 2" out of the ground!

Another one (there are 4 in there- two red, and two yellows) is just peeking out (looks like a man coming up out of a manhole cover seeing if the coast is clear), and a third must be heading up since the ground is cracked there. Not sure about the 4th one; I had a 'flat' bulb on that one so it may be a dud.

But how exciting is THIS?!! Pix soon!

Animals don't bother narcissus, fritillarias, and colchicum, and they're not so keen on alliums. But insects have different tastest and there are insects that will munch on all these otherwise poisonous bulbs. Lily beetles are a pain, stop them in their tracks before they breed and decimate your plants.
