One of our members spotted this specimen recently and reported : Linda Gilkeson claims that this beetle does no great harm to the garden, although it can munch away at conifers. It was dead when found beneath a Douglas fir. This beetle and its larvae could be destructive if found in large numbers, but it is usually rare. According to Cranshaw, Whitney, 2004, Garden Insects of North America, this species of beetle, Polyphylla decimlineata, is attracted to lights and they may audibly hiss when disturbed ! This specimen is likely a male. Photo: Derek Simkins, Vancouver MG
