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.
Horned Aphid
A social aphid from East Asia that forms colonies defended by sterile soldier nymphs with horned heads. They live on styrax trees and produce a single soldier caste.
Did You Know?
Soldiers stab intruders with their sharp horns and inject a toxic secretion, dying in the process like a honeybee's suicide sting.
