When I was young, in the 1960's and 70's, my parents garden, in the suburbs of SE London, had plenty of interesting insects. The violet-bordered ground beetle, Carabus violatus, was quite common. However, I fear that it may now be extinct in our local area, I haven't found one around my area in 40 years.
I suppose the fact that it is flightless means that it cannot easily recolonise areas once it has gone. Does anyone still have this beetle in their part of the UK?

I have not seen one of these beetles, for quite some time, they used to be common in my parents back garden. One website gives the U.K status as common and widespread?. One of our largest species I believe.

Thanks for the map, it seems to suggest C. violatus is still widespread in the UK. I think that I shall search further afield next spring and summer and see if I can find any specimens in wilder parts of Kent or Surrey.

Good luck in your hunting, I too, will see if I can find this impressive species next year in Wilts.

Is this an accurate *current* distribution or, as I suspect, a compilation of all known verified records from the past? Adam. |

I agree Adam the Carabus violaceus map does not actually state when the records go back too, although it does give a list of over 9000 sites, which does suggest the beetle to be widespread and common. I suggest it one of those things that you have to especially look for.

violaceus is quite common...still. They are more easy to find while overwintering or if you use pitfalls...3 weeks ago they were still active in E London, Cambridgeshire, Northamptonshire. Not sure if now, the temps went down...
If you are member of AES, get a paper with records. There is many recent ones...
