Description
 
 

Golden-eyed lacewing is a small, very common, typical green lacewing. It occurs in Mexico, in Central America, and throughout North America. It is the most common lacewing in eastern North America. It is common in Minnesota. They are found from May through October on grass, weeds, and shrubs, in fields, meadows, and other relatively open areas.

Adults are soft-bodied and small, ½ to 916 (12 to 14 mm) in length. The body is long and slender, and has a delicate appearance. The thorax and abdomen are pale green. There are small dark spots on the exoskeletal plate (pronotum) on the upper side of the thorax.

The upper side of the head (vertex) has two pairs of black spots. The lateral groove on the vertex near the margin of the compound eye is completely pale. The upper part of the face (frons) has a black mark. This mark appears as two bold crescents, one below each antennal socket, that meet between the sockets; and a thin line that runs around the outer and upper sides of each socket. There is a red Y-shaped mark between the antennal sockets with arms that stretch well above the sockets. The compound eyes are hemispherical and golden or copper colored. The antennae are hair-like and two-thirds as long as the body. On the base of each antenna on the lower half of upper side there is a reddish band. The band is not separated by a black X-shaped mark. The second antennal segment has a black ring.

The wings are pale green and clear with many green veins and many black cross veins. They are at least 25% longer than the body. They appear to be hairless, but there are short hairs along the margins and on the veins that are visible only under magnification. The forewing appears to have just one radial sector. The subcosta vein (Sc) and the anterior branch of the redius (R1) are not fused at the wing tip. The cross veins at the leading (costal) margin are not forked.

Third stage (instar) larva is alligator-like in appearance and ¼ to 5 16 long. It has long, sickle-shaped mandibles and well-developed legs which allow it to move quickly.

Season

 
 

Three generations per year: May through October

 
     
 

Behavior

 
 

Adults are nocturnal, active from sunset to sunrise. They are attracted to lights. They may emit an unpleasant odor when handled.

 
     
 

Life Cycle

 
 

The female lays eggs singly on foliage. She can lay two to five eggs per day and several hundred over her lifetime. The eggs are oval and held at the end of long, slender stalks. They hatch in three to six days and the larvae pass through three instars in two to three weeks. They pupate in a silk, pea-shaped cocoon. Pupa overwinter in the soil and adults emerge in the spring.
