Everyday Inspiration from a Small World

I am always on the lookout for patterns and textures.  I found this chunk of wood in the yard a few weeks ago.  I had to look twice when I picked it up : It looked like someone had carved a message into it.   Someone did, but it's a language I don't recognize / understand.

What do you think it says?
     Is it an old love letter?
     Bug History?
     Bug Stories?
     Trade records from bug culture?
     Schematics from an elaborate bug machine?
     Personal bug journal entries?

     Or just a hungry / nervous bug making it's mark in the world?
