INTRODUCTION The buttoned snout moth is a UKBAP priority species 38 and is classified as National ly Scarce 2 CURRENT STATUS 21 UK and Wales This moth was formerly widespread throughout southern Britain including South Wales and northwards to Lincol lfalfa snout beetle (ASB), Otiorhynchus ligustici , was brought to North America from Europe during the 1800s in shipping ballast and was first introduced in the Port of Oswego, New York. When a Glacial Erosion. As glaciers travel over land, glacial ice can erode the underlying bedrock.. This erosion can happen by:. Plucking. A. brasion. Plucking. This occurs when melt water at the base of the glacier freezes in cracks and fractures the underlying bedrock.. Presented by Calvin Wight. http://. solarviews.com. /cap/earth/. chile.htm. Outline.
