Elongate Paederine
A very slender, reddish-brown paederine rove beetle that lives deep within waterlogged soils near streams. Its extremely narrow body is adapted for burrowing through saturated soil.
Did You Know?
This beetle can survive prolonged submersion in water, breathing through a plastron of air trapped by microscopic hairs on its body surface.
Ponderous Borer
One of the largest cerambycids in North America, this prionine breeds in the roots and lower trunks of dead ponderosa pines. Adults are dark brown with a somewhat rough body surface. They are nocturnal and attracted to lights.
Did You Know?
Larval development can take up to six years in dry dead wood, one of the longest development times for any beetle.
