Arpedium cribratum
Arpedium cribratum is a small rove beetle (Staphylinidae: Omaliinae) in the Quadrum species group. It is one of four arthropods identified as a possible subnivium specialist—organisms that have evolved to live in the air gap beneath winter snowpack and appear rare or inactive during summer. The species is transcontinental and boreal in distribution, occurring across northern North America.
Bombus sylvicola
Forest Bumble Bee, Forest Bumblebee
Bombus sylvicola, the forest bumble bee, is a North American bumble bee species with a broad distribution across Canada and Alaska, extending into the western contiguous United States. In California, it occurs only at high elevations, making it a high-altitude specialist. The species has been identified as particularly vulnerable to climate change, with rising summer temperatures threatening its populations. Research indicates that B. sylvicola is among the cool-adapted bumble bee species experiencing decline due to warming temperatures.
