MYN – Clubtail exuvia (ventral view)

An Anisoptera exuvia was collected by Freda van den Broek on 10 June 2019 along the Red Cedar River in Barron County, Wisconsin USA.

This specimen is definitely a member of Family Gomphidae (Clubtails), possibly Rusty Snaketail (Ophiogomphus rupinsulensis).

Tech Tips

This subject was photographed against a pure white background (255, 255, 255) using the “Meet Your Neighbours” (MYN) technique.

Seven (7) photos of the specimen were taken using an aperture of f/16; in-camera focus peaking was used to highlight select areas in each photo. Adobe Photoshop CC 2017 was used to create the focus-stacked composite image shown above.
