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.
Milkweed Bug
A medium-sized bug with bold orange-red and black warning coloration. It feeds on milkweed seeds and sequesters toxic cardiac glycosides for its own defense.
Did You Know?
This bug has become a widely used laboratory model organism because it is easy to rear, has no diapause requirement, and displays clear warning coloration.
