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.
Flat Silphid Beetle
A flattened, all-black silphid beetle with three raised ridges on each wing case. It feeds on snails and caterpillars rather than carrion.
Did You Know?
Unlike most silphids, it has shifted entirely to predation and is rarely found on carrion at all.
