Tooth-Necked Fungus Beetle
A heavily armored, warty brown beetle that feeds on shelf fungi on dead trees. Males have two prominent horns on the thorax.
Did You Know?
It plays dead so convincingly that it is nearly impossible to distinguish from a piece of bark.
Silver Birch Web-Spinning Sawfly
A flat-bodied sawfly with long filiform antennae and a broad head. Larvae roll or fold birch leaves with silk and feed within the shelters.
Did You Know?
The flattened body shape of pamphiliid sawflies is an adaptation that allows adults to squeeze into tight spaces in leaf litter and bark crevices.
