Good Afternoon Q
becausse it is bullshit, wall would have no effect, infact they migrate at 1000 ft
During fall migration, migrating Monarchs (Danaus plexippus) have been seen flying by tall buildings such as the Empire State Building at more than 1,000+ feet. Butterflies are picked up by storm fronts and moved hundreds of miles, probably at altitudes of several thousand feet.
Migration and Overwintering. Monarchs can travel between 50-100 miles a day; it can take up to two months to complete their journey. The farthest ranging monarch butterfly recorded traveled 265 miles in one day.
Look at the hands and feet, OMG
