itch mites?
I want to document a complicated mystery where one thing leads to another, and I begin the lyric to "vision quest one."

I had some hours alone, a taste of a peaceful day.
I saw a tree full of crows that followed a hawk of prey.
From one tree to another this hawk carried his meal.
To the next tree they’d follow.
Like stool pigeons they’d squeal


A few weeks later I found a tortoise carcas cleaned out under one of the trees.
The leaf shading it had these strange nipple growths. The other leaves were clear.
I've had an extended contemplation of this condition and extending itching since then because...
The mites that cleaned out the tortoise shell laid eggs in the leaf. The nipples are called "galls."
The hawk dropped the tortoise.
