What characteristics identify green lacewings in the adult stage?

Adult green lacewings (family Chrysopidae) are characterized by several distinct physical features:

• Body and Size: They typically have a slender body that is yellowish, green, or gray in color, sometimes featuring specific markings. Adults generally measure between 1 to 1.5 cm (0.4 to 0.6 inches) in length, with a total wing expanse ranging from 31 to 65 mm.12
• Wings: They possess two pairs of similar, delicate wings featuring a complex network of veins that gives them a lacy appearance. When at rest, these wings are held rooflike over the abdomen.12
• Head and Sensory Organs: Adults have a small head with long, filiform (threadlike) antennae and prominent, iridescent golden- or copper-colored eyes. They possess biting mouthparts and are hypognathous (having the mouthparts directed downward).12
• Defensive Mechanism: Adults are sometimes referred to as "stinkflies" because they can emit a disagreeable odor as a protective device when threatened.1

These insects are widely recognized for their role in biological control, as their larvae are voracious predators of garden pests like aphids.1
