Abstract
WITH a few exceptions1, almost all the remarkably frost-resistant insects have been shown to contain glycerol or sorbitol2. The overwintering pre-pupal larvæ of a sawfly, Trichiocampus populi Okamoto, however, were found to survive freezing at a liquid gas temperature without any polyhydric alcohol. An extraordinarily large amount of a sugar, trehalose, was detected in this insect.
