Water stick insect

(Ranatra linearis) 2in long

Although large and common, this relative of the water scorpion is rarely seen due to its ability to remain motionless and imitate a stick among reeds and stems, awaiting its prey. Equipped with mantis-like front legs, which enable it to ambush any aquatic creature that ventures into range, this long brown insect also has a thin ‘tail’ that protrudes above the water and acts as a snorkel.
