The name of the Genus Graptodytes means: "Painted diver" (Greek Grapto - painted, dytes - diver). The specific name pictus is Latin for "painted" (think of: picture). So there is a double nomination of the striking colour pattern of this beetle. But the small size (2.2 millimeters) makes this pattern less conspicuous to the naked eye, at a first glimpse it's just another one of those many tiny diving beetles...

Graptodytes pictus on the suface

A funny thing with this little beetle: when in a tiny aquarium it swam a great deal of the time vertical, with its head above the water, something I haven't seen with other beetles (see picture in the middle). Now and then the beetle rested floating on the surface, as shown on the left picture.

When Graptodytes pictus is respirating at the surface, so as seen from behind, it looks a bit like a wasps head (right picture).
