While tooling around Cades Cove, we came across some coneflowers.  We were attempting some macro shots of those when we noticed some aphids crawling all over the underside of the flowers and stalks.  

They were quite a challenge to photograph as they were in a dimly lit area, moving...and I had no flash.

I cranked my ISO up to 1000 and shot at a large aperture of F/4 to get a shutter speed that might not cause any blur.  I managed to get a shutter speed of 1/250th.  That might seem fairly quick, but with these guys moving and the wind blowing it was very difficult to find them still.

I ended up with a few shots of them I liked, so I thought I'd share one with you.  This was taken with my Tamron 90mm Macro Lens and Sony A7R DSLR.
