Passion vine butterfly at rest

I saw this passion vine butterfly resting one windy late-afternoon. It didn’t seem in any rush to head off into the wind again so I got some decent photos. What I like about the photos is that I was close enough to get clear images of the butterfly’s labial palps, the white appendages sticking up on either side of the proboscis. These palps are covered with hairs that are believed to allow the butterfly to sense whether something is edible or not.
