Cannot see the front but I think it is a Lucanus cervus - Stag beetle? Do you have any rotting wood? as they like to live in it. In the UK they are mostly found in south and south east England. I hope I am not wrong as they are considered an endangered species.

Garden chafer, according to my insect book - not something you want on your plants, they eat leaves and flowers, particularly on fruit trees, but probably your beans as well. Book says they often swarm in June and July, specially if its hot.

Well yes there is probably some around here somewhere, but it is not like a stag beetle as I know it, this is only the size of the nail of my little finger. I didnt know there were others.

Thanks Bamboo. Looks like I will have to keep my beady eye on my beans then. They were fine yesterday but today are looking a mess where they have been chomping.

Shame wrong kind of Beetle.

Never mind, good try
