Blush in the rush

So I've been to this Fata Morgana, a glasshouse in Prague with rare butterflies (mostly alive) exposition. Pretty and everything, but much, much more people than butterflies in not-so-large area. Dragged by the crowd I couldn't make but a few pictures of these shying creatures with closed wings. It even left a blush in the frame, or is it messed-up white balance?
