I was thrilled to see my first antlion larva (Myrmeleontidae) in Panama. These amazing creatures are normally invisible to the observer, lying completely covered in the bottom of a pit of sandy soil. When insects cross the pit, the larva kicks sand against the walls of the trap, sending the hapless victim tumbling down to its massive jaws.
