Insect winter ecology describes the overwinter survival strategies of insects, which are in many respects more similar to those of plants than to many other animals, such as mammals and birds. Unlike those animals, which can generate their own heat internally ( endothermic ), insects must rely on external sources to provide their heat ...
In late autumn and during winter, they retreat down from the top 5 cm of soil and burrow down between 50–200 mm into the soil. During this phase, the grubs undergo a colour change from grayish/white into a yellow/cream colour. Once they reach the appropriate depth, the grub empties its stomach and starts to form a smooth oval shaped cell.
Within 7–21 days the grub will eventually die and as the grub decomposes, billions of new spores are released into the soil. Milky spore in the soil is not harmful to beneficial insects, birds, bees, pets, or people; and milky spore, like other bacteria, is highly survivable in drought conditions but suffers in temperatures of Zone 5 and colder.

Winter is a time when plants are often dormant, and missteps can lead to more harm than good, says Ponce. “A common mistake, for instance, is overwatering,” he adds.
Do Planters Need To Be Brought Inside During Freezing Temperatures? Plants that go dormant (both herbaceous and woody perennials) can be kept in containers over the winter months with some extra care.
Rest (winter dormancy) is a kind of physiological dormancy maintained by agents or conditions within the organ itself. However, physiological subdivisions of dormancy do not coincide with the morphological dormancy found in white spruce ( Picea glauca ) and other conifers (Owens et al. 1977). [ 10 ]
Witchetty grubs (Endoxyla leucomochla) of the subfamily Zeuzerinae. This family includes many species with large caterpillars and moths with a wingspan from 9–24 cm (3 + 1 ⁄ 2 – 9 + 1 ⁄ 2 in). [citation needed] These moths are mostly grey; some have long, narrow wings and resemble hawkmoths (Sphingidae) which are more advanced ...
