Been asking around but nobody seems to know this - would anyone here have any information on the weight or lifespan of either the Acraga coa (jewel caterpillar) or Gynaephora groenlandica (Arctic woolly bear moth)? The Arctic woolly bear moth’s range extends to the Arctic Circle, in Canada and even Greenland. If there is one charismatic Arctic invertebrate, it has to be the Arctic woolly bear moth, Gynaephora groenlandica (Wocke, 1874; Lepidoptera: Erebidae: Lymantriinae). Woollybears are the caterpillar stage of medium sized moths known as tiger moths. The woolly bear caterpillar’s life-span is up to 14 years, the longest life-cycle of any butterfly or moth. The Caterpillars produce Anti-freeze During the winter, the Arctic Woolly bear … The arctic woolly-bear caterpillars are unique for their adaptations to the cold arctic. The Arctic Woolly Bear can live up to seven summers. The Arctic woolly bear caterpillar can live for 14 years, feeding during the summer … The scientific name for the Arctic Woolly Bear moth is Gynaephora groenlandica. Body temperature and behavioral thermoregulation of high arctic woolly-bear caterpillars and pupae ( Gynaephora rossii, Lymantriidae: Lepidoptera) and the importance of sunshine. They are mainly found in the Holarctic in alpine, Arctic and Subarctic regions, and are best known for their unusually long larval development period. Gynaephora groenlandica, commonly referred to as the arctic woolly bear moth, is an erebid moth endemic to the High Arctic, specifically the Canadian Archipelago and Greenland. Woolly Bear Moth Caterpillar. Black spots mark its abdomen and yellow wings. Its caterpillar life cycle may extend up to 7 years with molting occurring each spring. It is best known for its slow rate of development, as its full caterpillar life cycle may extend up to 15 years. Due to the harsh conditions in the Arctic Tundra, and the short growing season, it can take up to 14 years for the Arctic Woolly Bear Moth to grow from an egg into a moth. While in dormancy, the larvae can withstand temperatures as low as −70 °C. A relative of our Woolly Bear, the Arctic woolly bear moth (Gynaephora groenlandica), actually has a life cycle that involves repeated freezing and thawing. In such conditions, a caterpillar has to overwinter in its larval form. This moth is best known for its slow rate of development. They spend about 90% of their lives frozen, though during June, they eat and eat in order to prepare for the next winter, which has just left and is about ready to come again. The larva to this moth is one we all recognize as the Woolly Bear ! This far north, the shortages in vegetation mean that food does not come easily and so the woolly bear has to spend a long time frozen. Gynaephora is a genus of "tussock moths", also known as the Lymantriinae, within the family Erebidae. This species remains in a larval state for the vast majority of its life. They spend nearly 90% of their life frozen and only about 5% feeding on the tundra during the month of June. The length of time that the moth lives in these earlier stages of development will depend on habitat, climate and weather conditions according to the Lepidopterists’ Society. G.groenlandica is one of two species in the genus Gynaephora occurring in North America.
