I have found this species of beetle in great abundance here on the Penllŷn and in most months of the year as an adult, we even found one on the coast path above Nefyn beach at Xmas ! In recent weeks I have been finding large numbers of the larva feeding on Cleavers or Goosegrass ( Galium aparine) as its sometimes called. In my native Yorkshire its also know as sticky willie !
The bloody-nosed beetle is one our largest leaf beetles which can most often be found, in spring and early summer, walking slowly over grassy areas. The beetles gets its common name from a defensive behaviour of exuding a foul-tasting bright red fluid from its mouth to deter birds and other predators. The top photo shows the adult and the other two show the larval stage feeding on Cleavers.
