Slender Spreadwing damselfly (female)

The following gallery of photos features a Slender Spreadwing damselfly (Lestes rectangularis) spotted near a vernal pool at Huntley Meadows Park (HMP). This individual is a female, as indicated by its terminal appendages and the ovipositor located on the underside of the posterior abdomen. The ovipositor is used to insert eggs into vegetation (endophytic oviposition).

Look closely at the tip of the female’s abdomen. Notice a couple of anatomical structures: two cerci (sing. cercus), superior appendages that have little or no function; and two styli (sing. stylus), structures that serve as sensors (like “curb feelers“) in egg positioning during oviposition.

The last two photos provide a good side view of the ovipositor.
