we found what I think is a type of beetle . . . but can’t find any information about what kind of beetle it is — can you help us? My wife found this beetle in her backyard when she was planting flowers. Thanks,

Hi Randy,
This is a female Broad Necked Root Borer, Prionus laticollis. According to Bugguide: “Eggs are inserted into ground (or under litter) in groups. Larvae tunnel downward to feed on living roots of a variety of trees and shrubs. At first they may feed on bark, but then proceed to hollow out small roots. Pupation occurs in spring, about 10 cm under the ground. Life cycle probably three years.”

    I just spotted one of these while driving out to a pet sitting job. It was big enough to see from the car! I stopped to check it out and helped the big bug over a stone wall. Very interesting! I’ve never seen one this big before. It was at least two inches long.
    I’m glad you have some good photos here. It was hard to find out what this bug was.
    Thank you!
