As a follow-up to last week’s preview, here is the complete story of my recent encounter with a Bold Jumping Spider (Phidippus audax) and a female Eastern Pondhawk dragonfly (Erythemis simplicicollis). The photos are a bit graphic, particularly for those of us who like dragonflies, but they illustrate the reality of nature that even super predators like dragonflies can easily become prey.
As I was walking at my local marshland park, I spotted a bright green dragonfly perched on the boardwalk and suspected immediately that it was a female Eastern Pondhawk. I moved in slowly to get a shot and was a bit surprised when the dragonfly did not take off when I got close. This is the initial view I had of the dragonfly.
I looked closely at the dragonfly and noticed that it was lying on its side and appeared to be dead. Wondering what might have caused its demise, I picked up the dragonfly’s body to do some amateur forensic analysis. (I obviously watched to many televisions shows about crime scene investigations.) As I lifted the body toward my eyes, I was shocked to find that a fuzzy black spider was still attached to it. Apparently the spider had been hiding in the gap between the boards as it feasted on the dragonfly.
Somewhat in shock, I dropped the dragonfly back onto the boardwalk and the fall caused the spider to be separated from its prey. Undeterred, it quickly set off to recapture the dragonfly.
The spider grabbed the dragonfly in a headlock and began to drag it back toward the gap between the synthetic boards of the boardwalk. It seemed totally oblivious to my presence.
When it reached the gap, the spider paused for a few seconds, as though considering possibility of dragging the body through the gap.
The spider decided to give it a try and did its best to pull the body in, starting with the head.
Despite the spider’s best efforts, however, the dragonfly’s body was simply too big.
As I left the scene, the spider had again settled down out of sight below the surface of the boardwalk, happily enjoying its meal and presumably hoping that it would not be disturbed again.
