Last summer I took quite a few shots using my butterfly vision (BV) filter, since found out that bees and bumblebees seem to be very fond of visiting Topinambur flowers (Helianthus tuberosus, also called "Jerusalem Artichoke") [the roots were used in former times here to make that famous Topinambur liquor]. So today here a few shots, to reveal in more detail, how that flower looks like and the very prominent UV pattern it has.
