I wouldn't have noticed this huge bug, except for looking to see what Odie was about to pounce on. He has a nose for trouble!
I don't care for bugs, but this one gave me a mixed ahhh - ewww response. Fascinating, but ewwww, it's a bug. You can see why it is called a Longhorn Beetle.
Here's another picture for some size perspective. It's body is about 2" long without counting the antennae. It is considered a musk beetle (ie. stink bug): No biting, stinging, or poisoning. It flies, so there could be heart failure concerns! Trivia facts: You can tell the male by the antennae being longer than the body. There are about 20,000 species of this bug, 412 of which are in Texas. Now we know.
