At the moment, Iolaus trimeni or Trimen's sapphire is probably my favorite butterfly to photograph. Their white underside is remarkably difficult to see against the shiny dark green leaves of the small trees they tend to prefer. Usually they go to small hilltops and settle as high as possible, which can make photographing them quite frustrating. One sees an electric blue flash as they circle around and then they settle just out of reach.
Fortunately, I have found a place where the highest bush has a huge boulder right next to it. It's not really their favorite place, but when they do settle there one can get slightly higher than them and get a photo from above.
Like many of the blues, they have an eye spot and fake antennae on the hind wing. Here is a picture of one bitten right on the eye spot.
