Hello,
My experience in "our" zone is:
the adults are busy laying eggs, which will be born in early spring.
The adults are dying off w/ temperatures. There may be a few leftout there where temps are warmer.
I was shocked this last spring to find baby slugs eating the plants before the ground was even unfroze. I had not been able to do anything in this part of the garden, because it was froze solid. They must be able to "hatch" in very cold temps. Simply, dismayed.

The "hosta" are still growing roots where the ground temp is at 50-55 degrees.

I live in TN- so I'm sure things are a bit different here. However, last Spring we got a late freeze, and it got my Hostas as they were starting to grow. They turned into what looks like frozen/wet cabbage. I just clipped the dead/damaged leaves, and let them be. About a month later they were happily growing!

a bit of drama i presume????

are you calling DORMANCY .. >>>> ..... DEATH ?????

i ask .. before i disabuse you of death .. but would prefer to avoid all that typing ...

I am not at all worried, concerned, wondering about my hosta, they are all asleep and will remain so for about 6 mos. I am wondering, hoping, PRAYING the dang slugs all got froze solid.
I know they lay eggs which hatch the following spring. What I don't know is if they hibernate like the frogs?
