Insects of Newfoundland and Labrador
​Insects established on the Island of Newfoundland represent mainly post-glacial immigration from the mainland, with numerous European introductions. With Labrador representing the easternmost limits of the arctic, sub-arctic and mainland boreal regions of North America, insect assemblages in this part of the province can be unique. Currently, more than 4,700 terrestrial insects, representing 21 orders, have been recorded in Newfoundland and Labrador

Overwintering Butterflies: Family Nymphalidae
This family of butterflies actually spends the winter in Newfoundland hibernating in rock and tree crevices. These butterflies have a longer life span and can live 10 months or more. We can encourage this natural behavior by creating Butterfly Shelters . These shelters can be constructed by stacking logs in piles in a backyard habitat. Landscape fabric can be used in between the layers of logs to provide even more dark, dry, and secluded cavities for butterflies to hibernate.

-
Small space? no problem try filling planters with nectar-rich flowers
-
Select native flowers abundant in nectar
-
Include a mixture of early and late bloomers
-
Remember to provide a source of water for butterflies such as a shallow dish or bird bath

Butterflies prefer plants with large petals that provide a perch

Gov NL - Fisheries, Forestry and Agriculture: Insects & Spiders
Insects fulfill many roles, and often directly or indirectly affect humans. As pollinators, they are irreplaceable for the continued viability of numerous plant species, but insects can also be vectors of disease and significant consumers of plants, some of which are important resources for people. Other insects play essential roles in nutrient cycling, biological control, and are an important food source for other animals.
