A New Reason To Care About The Wooly Bear

O! Pyrrharctia isabella (known
To schoolkids, fondly, as the Wooly Bear,
For its appearance ere it's fully grown
Into a moth)! This caterpillar's rare
Skill set, while not including future-sight
Into how bad the winter's going to be,
Is greater than we thought! That it can fight
Off freezin' through that season, we agree,
Is cool. Now per Carl Zimmer's column, Loom,
An infestation of cater-cooties
Is something they can live through; they consume,
And thereby press into diff'rent duties,
Some plants containing poisons, which become
Their medicine, and suddenly taste - yum!
