6965. I’m trying to identify this beetle I found on the sidewalk in Maple Ridge, BC (July). It’s about an inch long. My husband thinks it’s a Colorado beetle but the photos don’t quite match. Would it eat our potato crop? Any help would be appreciated. Maple Ridge, BC. Canada
Number 6965. This is a ten-lined June beetle, Polyphylla decemlineata (Coleoptera: Scarabaeidae). These will not harm your potato crop, but their larvae can cause damage to tree roots. Click here for more detailed information.
