Sinossi
Excerpt from Notes of Observations of Injurious Insects: Report, 1879
An idea being prevalent that cold kills the grubs, I took the opportunity whilst the great cold lasted of examining the state of all larvae and pupae I could find fully exposed to its influence, whether unsheltered, under bark, or in frozen ground, and found that in all cases, even where the earth was frozen so hard that the mass had to be broken up with a hammer, and the larva} or pupae were perfectly rigid, that on thawing they did not appear to be in any way injured; and in the case of the larvae of the Cabbage Weevil (which was the only instance in which any immediate action was to be expected) they continued the operation of making their earth - cases for pupation (as is usual with this grub on disturbance from the gall) as if nothing had happened. Of these observations I give the details under the headings of the respective insects.
