I found only one of these fellows on a weedy grass stem which was surprising since I find most beetles on flowers eating the tender petals . There were not many flowers left on this bike path trail margined in grass and weeds . I really don't know what kind of beetle this is . It seemed lazy as it did not try to fly away as I severed it's grass strand so I could take better photos of it . On closer analysis , I saw that it was feeding on the grass stem with a huge swordlike mouthpart ... glad I did not hold this one ! I would appreciate any comments or information on this fellow , thanks , sincerely Beth
