Western Encephalitis Mosquito
A medium-sized mosquito with a distinctive white band on the proboscis and banded legs. It is the most important vector of Western equine encephalitis and St. Louis encephalitis in western North America. It breeds in a wide variety of sunlit and shaded water sources.
Did You Know?
Its feeding behavior shifts seasonally from birds in spring to mammals in late summer, which drives encephalitis virus spillover to humans.
Agonum Marsh Ground Beetle
A medium-sized metallic green ground beetle with pale-margined elytra found exclusively in wetland habitats. It runs rapidly on wet mud and vegetation near water.
Did You Know?
It is so dependent on wetlands that its presence or absence is used by ecologists as an indicator of wetland habitat quality and hydrological integrity.
