Good or Bad Omen?

This guy was sitting on the window next to my favorite table in the library when I walked up this morning. I feel there's a saying tied to seeing a praying mantis, about them being a good luck charm or something like that. But as a biologist I know these guys as being shady-as-f#@& and big ole bastards that eat the heads off their mates.

Part of me thinks this is a good sign for the start of my day.

The biologist part thinks I should find another table.
