A tiny beach mystery

It was a cloudy day on the Washington coast, the breeze blowing the sound of the waves up the wide expanse of beach. Past the part of the beach that you can drive cars on(!) it was relatively quiet between the surf and the red cliffs. Lost in conversation or my own thoughts, I never would have noticed this unusual scene if my companion hadn't pointed it out. A single ladybug (ladybird, if you wish), was slowly walking along the sand. If you look closely, you can even see the trail it's leaving behind it. What brought it there? Was it in love with a sea turtle? Did it need a break from the rat-race of chasing aphids in the garden? It didn't say.
