Identification

The plate between the bases of the wings (scutellum) is triangular and shorter than the first thoracic plate (pronotum).

The abdomen is wider in the back (distal) half than the front. The enlarged lateral margin of the abdomen (connixivum) is smooth, not notched. It is not dilated.

The wings at rest are held folded over the back. Thye cover only the middle portion of the abdomen, leaving the sides exposed.

The collection of protruding mouthparts (beak) is optimized for sucking. It is short and has three segments. The antennae have four segments. The last segment is only slightly enlarged (clubbed). There are two compound eyes and two simple eyes (occelli).

About

Published on Aug 27, 2015

This video features an ambush bug consuming a honeybee nearly twice its size. The Ambush Bug, Phymata americana, is a member of the Assassin Bug family. Adults hang out on leaf heads of goldenrods, asters, etc., awaiting prey. When a small insect approaches, the Ambush Bug shoots out its chunky, scissor-like forelegs to secure the prey, which is then immobilized by injecting poison through its piercing mouthpart.
