Behemoth Blue Morpho Butterfly Menaces The Back Bay

Friday afternoon, a giant blue butterfly terrorized workers in Boston's Back Bay. The giant insect clung for an hour to the side of the Prudential Tower. The butterfly's wingspan dwarfed the width of the 749 foot  structure. The Pru, completed in 1964, was once the tallest building in the city.

No one seems to know where the insect came from or why it landed on the 52-story building. Local entomologists are speculating the Blue Morpho was attracted to the iridescent blue coloring of the glass and aluminum skyscraper.

Structural engineers have been called in over the weekend to ascertain the building's integrity.
