Test shots: Erythemis simplicicollis exuvia

An Eastern Pondhawk (Erythemis simplicicollis) exuvia was received from Andy Davidson, a graduate student at Virginia Commonwealth University.

This individual is a male, as indicated by the vestigial hamules visible on the ventral side of the exuvia, abdominal segments two and three (S2-S3).

Food for Thought

This exuvia is one of three “cast skins” from odonate nymphs that were collected in the field and reared in the laboratory as part of a research project entitled “Predator-Prey Interactions in a Changing World.” Since all three nymphs were collected from the James River rock pools, I assume they lived in essentially the same habitat. I wonder why the E. simplicollis exuvia is so much darker in color than either the P. flavescens or P. longipennis exuviae.

Tech Tips

The following equipment was used to shoot both of the macro photographs featured in this post: Fujifilm X-T1 digital camera; Fujifilm MCEX-11 extension tube; and Fujinon XF80mm macro lens. The camera was set for both manual exposure and manual focus. That’s right, a switch on the camera body is used to set the type of focus. It’s a Fujifilm thing. Actually, back-button focus was used to autofocus the image and adjusted manually as necessary. That’s also a Fujifilm thing.

Godox XProF radio flash trigger, mounted on the hotshoe of my X-T1, was used to control a pair of off-camera Godox TT685 Thinklite TTL Flashes (TT685F and TT685C) set for radio slave mode. Each flash was fitted with a snap-on plastic diffuser.

Adobe Photoshop CC 2017 was used to spot-heal and sharpen both images.
