Insects that survive subfreezing temperatures are generally classified as freeze-avoidant or freeze-tolerant. The general strategy adopted by insects differs between the Northern Hemisphere and the Southern Hemisphere. In temperate regions of the northern hemisphere where cold temperatures are expected seasonally and are usually for long ...
Nepa is a genus belonging to the family Nepidae, known as water scorpions.Species are found in freshwater habitats in the Northern Hemisphere. [2] [3] [4]They are oval-bodied, aquatic insects with raptorial front legs.
Notoptera, also known as Xenonomia, [1] is a clade of insects belonging to Polyneoptera. It contains two living groups, Mantophasmatidae (gladiators) native to southern Africa, and Grylloblattidae (ice crawlers) native to cold montane environments in the Northern Hemisphere. Both groups are wingless.
Woolly aphids occur throughout the Northern Hemisphere. Many of the numerous species of woolly aphids have only one host plant species, or alternating generations on two specific hosts. They have been known to cause botanical damage and are often considered a pest. While most damage is minor, they can spread plant diseases and fungi.
Boreidae, commonly called snow scorpionflies, or in the British Isles, snow fleas (no relation to the snow flea Hypogastrura nivicola) are a very small family of scorpionflies, containing only around 30 species, all of which are boreal or high-altitude species in the Northern Hemisphere. These insects are small (typically 6 mm or less), with ...

The most common bees in the Northern Hemisphere are the Halictidae, or sweat bees, but they are small and often mistaken for wasps or flies. Bees range in size from tiny stingless bee species, whose workers are less than 2 millimetres (0.08 in) long, [ 5 ] to the leafcutter bee Megachile pluto , the largest species of bee, whose females can ...
A few species (B. polaris and B. alpinus) range into very cold climates where other bees might not be found; B. polaris occurs in northern Ellesmere Island in the high Arctic, along with another bumblebee B. hyperboreus, which parasitises its nest. This is the northernmost occurrence of any eusocial insect. [25]
