Features and Behaviors
FEATURES
The lyre-tipped spreadwing is a medium sized (one to two inches long) damselfly with large eyes, long narrow wings, and long legs with a long tibial spur (claw) at the end of each. Both males and females have metallic brown markings on their thorax and on the top of their abdomen. Males have bright blue eyes and a light blue body, while females have brown to blue eyes on a bright yellow/white body. Distinguishing between the northern (Lestes disjuntus), southern (Lestes australis), and sweetflag spreadwing (Lestes forcipatus) is very difficult and requires differentiation between small differences in color patterns and abdominal structures.
BEHAVIORS
This species can be found in temporary wetlands and shallow marshes and on the edges of lakes and ponds statewide in Illinois. Eggs are lain in the fall, hatch in the spring according to light cues, and larvae live for one to two years before metamorphizing into winged adults. Adult males spend most of the time perched on the vertical stalks of plants. Females are followed into the air and mating lasts 25 minutes; usually in the afternoon, interrupted by several landings. Females deposit several hundred eggs over the course of an hour by backing down the stem of a bulrush into shallow pools of water. They can be seen in flight statewide from June to September.
