American Marsh Treader
A very thin, elongate bug with a head nearly as long as its thorax. It creeps slowly along floating debris and sphagnum mats at the edges of ponds and marshes.
Did You Know?
It moves so slowly and deliberately that it rarely disturbs the water surface, making it nearly invisible to predators.
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.
