I am probably all wrong about this, but I believed insects conducted their lives in total randomness. A fly accidentally discovers a pile of dog poop not because of it patrolled its neighborhood in a methodical manner. "Something smells good over there. Let's go see what it is."
So when my moth flittered away after the gecko stumbled on his lair, I expected that was the end of our paths crossing. However, when I returned this afternoon from the pool the giant moth had returned to the same place on my lanai wall. Same place!
Made me think that I might catch that cockroach lurking around my seat cushions.
I think that geckos have territories which they patrol in grid-like patterns. Look it up!
