This little beetle, Pterostichus madidus, is common in gardens but I suspect even if one saw it one would take little notice of it unless you have a particular interest as I do!
It is about one centimetre long (excluding the antennae) and is flightless. They are part of the family known as ground beetles and this species does live its life on the ground or on plants and it has a particular fondness for fruit, hence its colloquial name of the strawberry beetle. It is a shiny metallic black beetle but part of the legs are a brownish colour. The front legs have feathered notches at the end which are used to clean the antennae!
So, if you have a garden and have fruit plants keep an eye for this fascinating little creature during the summer months. In case you have not worked it out, there are two in this photograph, a mating couple!
