Identification

This is an elongated, nearly parallel-sided true bug. The body is ½ to 11 16 in length. Females, averaging long, are slightly larger than males, averaging 9 16 long. The overall body color is usually pale green, the color of a Granny Smith apple, but may be yellowish-green, yellow, or reddish-brown. There is a spine at both rear (distal) corners of the pronotum.

The head is elongated and has both large compound eyes and small simple eyes (ocelli). There is a transverse groove between the compound eyes. The protruding mouth part (beak) has 3 segments. It is short and curved. When at rest it is tucked into a groove between the forelegs. The antennae have 4 segments and are much longer than the head.

The third leg segment (femur) on the forelegs is thickened. There is a band at the end of the femur that may be dark or red and conspicuous or barely visible.

Life Cycle

 

 
Behavior

When hunting, the adult smears a sticky substance, exuded from a gland on the tibia, onto small hairs on the tibia. It then probes flower parts with its legs and eats small insects that stick to the legs. The forelegs are also well adapted for grasping larger insects.

Comments

Common
Of the five Zelus species native to North America, this is the most common.

Often Misidentified
Due to variation in body color, this species has often been misidentified in the past as Zelus exsanguis. However, that species is very rare. With the exception of a single collected specimen, all sightings of Zelus exsanguis in the United States should probably be recorded as Zelus luridus.
