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.
Columbia Silk Moth
A large reddish-brown silk moth closely related to the cecropia moth but found in northern bog habitats. Its cocoon is spun on larch branches rather than broad-leaved trees.
Did You Know?
It is one of the few silk moths adapted to boreal wetlands, where its larvae specialize on conifer needles instead of hardwood leaves.
