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.
