Haliplus heydeni , Syn. H. multipunctatus is a beetle from the family of water treaders (Haliplidae).

features

The beetles reach a body length of 2.5 millimeters. The top of their very short and wide body is shiny. The pronotum is very wide and two and a half times as wide as it is long. Unlike the similar teardrop-shaped water tread ( Haliplus ruficollis ), it has a clear transverse impression in front of the base between the very short and straight basal lines . The lines run parallel and only up to the middle of the pronotum. The upper wings have their widest point behind the shoulders and taper strongly towards the tip. They are provided with coarse dot stripes which, unlike the similar species, are marked with a larger dimple point at the base. The very fine row of dots next to the sash seam is much weaker than the others. The epipleurs are also provided with a series of rough points. The disc of the wing covers also bears blackish spots apart from the stripes. The furrow on the sternum of the prothorax is deep and smooth. The wings of the female are also shiny on the rear part.

Occurrence and way of life

The species is widespread in Europe, Asia Minor, Western Siberia and Turkestan . It is widespread in Central Europe and is common to very common. The animals live in clean, stagnant and slowly flowing waters.
