You reminded me of the first tomato bug I ever saw. I was a little girl and my folks had planted what was called (during the war years) a Victory Garden. Even in the city of Detroit, everyone had a small garden in their backyard.
Anyway, I was sitting on our porch, looked down and saw this giant green thing crawling up the stairs and panicked! I thought the world was probably coming to an end, but my dad said very casually that it was only a tomato bug.
They really are the ugliest of the uglies! Don't let them get you.
