Jumping spider

March 15, 2022

The following photo shows a tiny spider carcass (~3/16″ long) that was inside an exuvia (~1 3/4” long) from a Common Green Darner dragonfly (Anax junius). The exuvia was collected on 17 June 2021 from a small pond in Prince William County, Virginia USA. I discovered the spider long afterward — too late to save its life.

Thanks to Eva Weiderman and Joseph Girgente — members of the “Odonate Larvae and Exuviae” Facebook group — for their help in identifying the specimen as a jumping spider, Family Saticidae.

Salticidae is one of several families of spiders with eight (8) eyes. My take-away from reading the reference on BugGuide entitled “Spider Eye Arrangements” is identification of this specimen to the genus and species level is challenging at best and impossible at worst.

In contrast, it’s well known that spiders use odonate exuviae for shelter. I wish the jumping spider had come out of its most excellent hidey-hole sooner!

Tech Tips

The tiny jumping spider was photographed using a Panasonic Lumix FZ-300, Raynox DCR-250 close-up filter, Godox X2To/p flash trigger, and Godox TT685F plus Altura flash modifier. Camera settings: ISO 100 | f/7.1 | 1/60 s | 56.9mm (316mm, 35mm equivalent).

Raynox DCR-250 close-up filter” is a blog post in which I provide more information about how I use the Raynox with my Panasonic Lumix superzoom bridge cameras.

As I was photographing a female Autumn Meadowhawk dragonfly (Sympetrum vicinum) perching on the boardwalk at Huntley Meadows Park on 11 November 2014, I noticed a small spider moving toward the dragonfly quickly.

I remember thinking, “No way this smaller spider is preying upon a larger dragonfly.” Turns out the spider actually may have been stalking the dragonfly!

Apparently there is some risk associated with a dragonfly attempting to capture a jumping spider. Fitch (1963) observed an adult Phidippus audax (Hentz) jumping several inches into the air in unsuccessful attempts to capture adult dragonflies overhead and on other occasions observed P. audax carrying dragonflies. Edwards (1980) presents two additional records of P. audax and P. otiosus (Hentz) capturing adult Libellulidae. Source Credit: DRAGONFLY PREDATION UPON PHIDIPPUS AUDAX (ARANEAE, SALTICIDE). 1988. The Journal of Arachnology 16:121.

Thanks to the experts on BugGuide Facebook group for identifying the spider as a type of jumping spider, probably a male Phidippus sp. The screw hole in the boardwalk — an estimated 1/4″ in diameter — provides a sense of scale.

You can see the swollen pedipalps on either side of the “fangs.” That’s where the male spider carries his sperm. Also a female would have a larger abdomen to produce the eggs. Source Credit: Dennis Haines, BugGuide Facebook group.

In case you’re wondering how the close encounter turned out, let’s just say the dragonfly’s spider sense was tingling and she opted for flight rather than fight. Score one for Team Dragonflies!

I’m looking forward to using my new Raynox DCR-250 close-up filter to shoot some macro photographs of this type of spider.
