Please do not touch our butterflies

My girlfriend Michelle and I visited Wings of Paradise Butterfly Conservatory in Cambridge. I'm not a big fan of butterflies but when it comes to photography, they become one of my favorite models because 1. they are not as fast other insects or animals and 2. they are reasonably big so I don't have to get too close or too far while I'm shooting.

In the middle of the shooting, I was lucky enough to have a butterfly landing on me. It must have gotten attracted by my sweat since it was pretty warm inside the conservatory. So above is the picture of Michelle and I not wasting the opportunity.

When we finished and as we were leaving, we noticed that there was a sign near the entrance/exit saying "Please do not touch our butterflies". Oops but too late and too bad. I've already took all the pictures and it was the butterfly that approached to me. XD
