Composite image: “Generic Gomphid” (face)

larva/nymph in the Family Gomphidae (Clubtails) was collected by Bob Perkins from the New River in southwestern Virginia. The larva died before it metamorphosed into an adult.

An Ashy Clubtail dragonfly nymph was also collected by Bob Perkins. (The date and location where the specimen was collected are unknown.) The nymph was reared in captivity until it emerged on 21 March 2017 and metamorphosed into an adult female. This specimen is the exuvia from the nymph.

Although face-head of the “Generic Gomphid” and Ashy Clubtail look similar, they aren’t identical. More later after the specimen is keyed out carefully.

Tech Tips

13 photos were used to create the focus stack of the “Generic Gomphid.” A single focus point was positioned over select anatomical features; photos were taken at each point of interest.

The following equipment was used to shoot the composite image of the “Generic Gomphid”: Canon EOS 5D Mark II digital camera, in manual mode; Canon MP-E 65mm Macro lens (set for f/11 at ~2.5x); a Canon MT-26EX-RT Macro Twin Lite set for “Master” mode, and a single external flash set for “Slave” mode — a Godox TT685C Thinklite TTL Flash fitted with a Lastolite Ezybox Speed-Lite 2 flash modifier.

Auto power-off was disabled for the camera and external flash units.

Adobe Photoshop CC 2017 was used to create the focus stack, as well as spot-heal and sharpen the final output.
