This interesting beetle was found (I believe in the Ovenden area) by Julian Birkhead earlier this month. It can be up to 20 mm long and this looks to be a female as the male has a larger, upturned horn (projection) on its head. It feeds on sap on warm summer nights.
Julian says “The rhinoceros beetle is widespread but not common. You can see distribution maps on iRecord where I’ve logged my sighting of it: http://www.brc.ac.uk/irecord/record-details?occurrence_id=3618546. I once saw two, including a male, in Shibden valley ten years ago.”
