Greenish-Yellow Sitochroa Moth

I keep them in my garage in the winter. It's not heated, or insulated, and still gets pretty cold in there, maybe down to 15F when it's -20F outside, but they seem to do ok. I think the key is to keep them out of the wind, which would dessicate them if left outside here. The trickiest part is actually late Feb/March, when the sun gets higher - the garage starts warming up, but it's still too cold outside, so fungus can be a problem then. I've lost many plants over the years, but have had 100% survival the past couple years.

yes it is, which happens to be the host plant for this particular moth.
