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.
Balsam Fir Sawfly
A boreal sawfly whose dark green larvae with lighter stripes feed on balsam fir needles. Periodic outbreaks can cause significant defoliation in fir forests.
Did You Know?
Outbreaks of this species often follow those of the spruce budworm, as the already stressed trees are more susceptible to additional defoliation.
