This is the second time I have seen this beetle on my patio. Any idea what it is? It's gigantic (compared to other beetles in my region - outside of Philadelphia) and I have never seen one like it. For the first time, I have had a problem with Japanese beetles this year on my roses, so maybe it's an active year for beetles in my area. I would like to know what type of beetle (or whatever kind of bug) it is so I know whether it is considered a pest... and out of sheer curiousity.

Thanks!
