When I just-out-of-the-cacoon promethea moth showed up, I went outside to find a suitable background. That background came in the form of a large stump which I subsequently hauled into my studio.
With studio lights available, lighting this little subjects was not a challenge. However, keeping the entire moth in focus was. A square-on position with the wings is what is needed to accomplish this.
