Description:

A beetle, approx 8-10mm in length with the eye catching habit of walking upside down on the underside of the surface of a garden pond. (A sort of back-swimming bettle) Difficult to photograph because of the reflection of water, but on the elytra there are numerous fine longitudinal dark lines with a scattering of blackish spots.
