Small Capsid Bug on Nettle Leaf

When I first saw this tiny (3-4mm long) bug on a nettle leaf I assumed it must be Anthocoris nemorum, a small flower bug I had previously seen on nettles in that area (photo here).  However, on closer inspection, I realized that the pattern of light and dark areas on its back were wrong for A. nemorum.  Later, when I got back home, I was able to properly identify it as Liocoris tripustulatus (Hemiptera: Miridae) a capsid bug that is known to feed on nettles.
