A swath of Minnesota's forest heavily impacted by eastern larch beetle. Photo by Marc Roberts, USDA Forest Service. Eastern larch beetle (ELB) is a native bark beetle infesting tamarack (eastern larch) at unprecedented levels throughout the tree's range.
Adults emerge in late spring and bore into the trunk to feed, mate, and lay eggs. The current outbreak of eastern larch beetle in northern Minnesota is going into its 18th year, and researchers have found that at least some eastern larch beetles are able to reach maturity without requiring an overwintering period.
In short, warmer winters mean eastern larch beetle is killing trees faster than it can be managed. Eastern larch beetle-Management Tamarack infested with eastern larch beetles appear red.
The current outbreak cannot currently be managed on a landscape level due to the abundance of beetles, ecologically sensitive nature of most tamarack stands, unpredictable site accessibility for logging equipment, and poor markets for tamarack lumber.

Excerpt from Effects on Eastern Larch Beetle of Its Natural Attractant and Synthetic Pheromones in Alaska This publication reports research involving by: 4. An eastern larch beetle infestation can be recognized by the presence on the trunk of long flows of resin and dark brown boring dust from the galleries excavated by the larvae and adults.
During severe attacks, the numerous galleries excavated under the bark can disrupt sap flow, eventually causing the tree to become desiccated and die within. The eastern larch beetle, Dendroctonus simplex LeConte (Coleoptera: Sco!ytidae), occurs throughout the natural range of tamarack, Larix: laricina, its principal host, from Newfoundland and the northeastern United States to British Columbia and Alaska (WoodCited by: The eastern larch beetle is a native North American bark beetle that occurs throughout the range of its principle host, tamarack.
It is generally a secondary pest attacking stressed trees, but when outbreaks occur, healthy trees are also attacked. DISTRIBUTION. In Canada, the eastern larch beetle occurs in every province, plus Yukon and NorthwestFile Size: KB.
The seasonal development of the eastern larch beetle is shown in figure 2. One generation a year is produced by the eastern larch beetle in Alaska. Simpson () reports that as many as three broods were produced in New Brunswick in Prebble () states that.
The eastern larch beetle, D. simplex LeConte, occurs in the Northeastern States south to West Virginia and west to Minnesota.
It also occurs from coast to coast in Canada and northwestward to Alaska. Its preferred host is tamarack but it has also been recorded from red spruce.
The larch beetle is just the latest critter to threaten Minnesota trees. There have been recent outbreaks of native insect pests like pine bark beetles and jackpine budworms in the state.

Insects are typically drawn to a given area by available food supply, weather, environmental factors (pollution, etc), water supply, mating patterns, etc and can be territorial. im trying to find out the identification of a beetle in Alaska, I have been looking for awhile, its oval, about a 1/4 inch at most.
