Pine Bark Longhorn
A flat, dark grey-brown spondylidine beetle with longitudinal ridges on the elytra. Common in conifer forests across the Northern Hemisphere, it breeds under the bark of dead pines. Adults are nocturnal and hide under bark by day.
Did You Know?
Adults occasionally emerge from structural pine timber in buildings, sometimes years after the wood was milled.
Giant Brazilian Ant
A large ponerine ant found in the cerrado and Atlantic Forest regions of southern Brazil, Argentina, and Paraguay. Like its congener D. gigantea, it is queenless with a dominant gamergate worker handling reproduction. It is a solitary forager, hunting individual prey items on the forest floor.
Did You Know?
When the dominant reproductive worker dies, subordinate workers engage in ritualized tournaments to determine the next gamergate.
