Cimbex femoratus, the birch sawfly, is a species of sawfly in the family Cimbicidae.
Cimbex femoratus can reach a length of 17–23 millimetres (0.67–0.91 in). The head is large, with large and strong mandibles. Wings are smoky brown with brown margins. The thorax is shiny black. The shiny black abdomen shows a whitish band and a large red-brown band, especially in males. The antennae are black at the base and yellow-orange at the tip. Even the last leg segments are yellowish. The adults fly in May to August.
Larvae are pale bluish-green, about 45 mm long and they look very similar to caterpillars. On the back they usually have a dark, narrow bluish longitudinal stripe. They can be found between June and September and feed exclusively on leaves of birch ( Betula sp.)
These sawflies prefer areas where birch trees can be found.
Firs are evergreen coniferous trees belonging to the genus Abies in the family Pinaceae. There are approximately 48–65 extant species, found on mountains throughout much of North and Central America, Europe, Asia, and North Africa. The genus is most closely related to Cedrus (cedar).
Larix laricina, commonly known as the tamarack, hackmatack, eastern larch, black larch, red larch, or American larch, is a species of larch native to Canada, from eastern Yukon and Inuvik, Northwest Territories east to Newfoundland, and also south into the upper northeastern United States from Minnesota to Cranesville Swamp, West Virginia; there is also an isolated population in central Alaska.
Picea glauca, the white spruce, is a species of spruce native to the northern temperate and boreal forests in North America. Picea glauca is native from central Alaska all through the east, across western and southern/central Canada to the Avalon Peninsula in Newfoundland, and south to Montana, North Dakota, Minnesota, Wisconsin, Michigan, Upstate New York and Vermont, along with the mountainous and immediate coastal portions of New Hampshire and Maine, where temperatures are just barely cool and moist enough to support it. There is also an isolated population in the Black Hills of South Dakota and Wyoming. It is also known as Canadian spruce, skunk spruce, cat spruce, Black Hills spruce, western white spruce, Alberta white spruce, and Porsild spruce.
Betula papyrifera is a short-lived species of birch native to northern North America. Paper birch is named after the tree's thin white bark, which often peels in paper-like layers from the trunk. Paper birch is often one of the first species to colonize a burned area within the northern latitudes, and is an important species for moose browsing. Primary commercial uses for paper birch wood are as boltwood and sawlogs, while secondary products include firewood and pulpwood. It is the provincial tree of Saskatchewan and the state tree of New Hampshire.
Cimbicidae is a family of sawflies in the order Hymenoptera. There are more than 20 genera and 200 described species in Cimbicidae. Larvae are solitary herbivores.
Tenthredinidae is the largest family of sawflies, with well over 7,500 species worldwide, divided into 430 genera. Larvae are herbivores and typically feed on the foliage of trees and shrubs, with occasional exceptions that are leaf miners, stem borers, or gall makers. The larvae of externally feeding species resemble small caterpillars. As with all hymenopterans, common sawflies undergo complete metamorphosis.
Arge pagana is a sawfly in the family Argidae. It is known by the name "large rose sawfly" although the related species Arge ochropus is also known by this name.
Psilocybe caerulipes, commonly known as blue-foot, is a rare psilocybin mushroom of the family Hymenogastraceae, having psilocybin and psilocin as main active compounds. An older synonym is Agaricus caerulipes.
