Aaron,
Wish I could. It may have been in one of the two mags I read-
Gleanings or ABJ. All I know is I was intriqued by it, that the
bees are resting in an ice cocoon. If I recall correctly, it was
not in contact with the bees but a short distance away and
usually formed at night.
I almost did not include it in my post because I anticipated the
question. Maybe someone else recalls it. It was several years ago
that I read it. It was a sort of throwaway in the article.
Nothing more was made of it than it was observed. I am not sure
if there was a supposition on insulation or not, but it seems
intuitive.
