Dalopius marginatus
One of 65 UK species belonging to the Elateridae group (Click Beetles) is Dalopius marginatus. The common name is extremely apt, as the beetle has the ability to flick itself upright should it fall onto it's back. It is able to do this by flexing a well developed joint between the first and second thoracic stermites. This also seems to be used as a defence mechanism if the beetle feels threatened. D. marginatus is a small Click Beetle, at around 9mm length and although quite inconspicuous, is a common species. Like most species, it particularly favours low vegetation.
