MYN – Clubtail exuvia (dorsal 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 Midland Clubtail (Gomphurus fraternus).

10 JUN 2019 | Barron County, WI | Anisoptera exuvia (dorsal)

Notice there are no mid-dorsal hooks. Lateral spines are located on abdominal segments six through nine (S6-S9).

The case for Midland Clubtail is looking stronger based upon a close-up of the prementum that will be published in my next blog post.
