We found an exciting little dung beetle in our garden Monday night (23rd July 2007) and would be grateful if you could let me know whether it has become more common in the last few years. Fortunately it is so distinctive there is no doubt about the identification and, even better, itís the only member of the genus in Central and Northern Europe. Illustrative sketch from Dave's notebook

Odonteus (= Odontaeus) armiger has a long horn on the head, movable at the base, which is very distinctive. Extracts from the entry on the RECORDER database as follows
