Battle of the Bugs: Monarch Butterfly vs. the Bark Beetle

When Pangaea, the supercontinent broke apart some 250 million years ago it allowed for the creation of seven unique land masses that fostered the growth of individual species that could survive and thrive in the warm or cool climates that had become their new habitat.

As species adapted to their environments there came to be a perfect Utopia of existence uninterrupted by intruders capable of threatening the elaborate ecosystems that had developed. 

That serene image was thrown into chaos shortly after man realized wooden structures float well and could potentially take you (and other unwanted species) to far off lands.  While exploration eventually led to shipping and the profitable business of imports and exports, our boxes filled with spices and linens brought with them some unexpected surprises.  Invasive plants and insects now had easy passage to new territory where they could flourish, annoy, and in some cases, destroy native species.
