I'd stay very still and let them flutter
I'd quickly jump behind my cars' radiator,that seems to stop em every time!
I was attacked by "butterflies" in my stomach when I fell in love with my partner. Beautiful feeling.
get my can of raid, get rid of them, go back to work. probably wonder where they came from what made them agressive.
you did say "attacked" that would be pretty annoying at the least.
i'll freak out!! i think its scary if they continue to increase in number O_O
I love butterflies they are so colorful and gentle...:) I would let them they may cool me off on a warm summers day with all their wings fluttering about hahah ;)
Run LAUGHING, I suppose!
