This seems to be a Grapevine Borer Beetle (Pelidnota punctata) as I found and photographed on this door screen last week. Their common name betrays their preferred plant and behavior, eating the fruit and even the leaves of grapevines, though apparently not to extreme pest levels. I was also not the only one to think about how it looks like a huge ladybug in some ways. You never know what new sorts of neighbors you will find even at your own door…
