Daily Postcard: A two-tailed swallowtail butterfly hangs upside down while sipping nectar from flowering sage plants at a residence Thursday in White Rock. Butterflies do not have mouths. Instead, they have a proboscis extending from the front of their head, a straw-like tube that coils up when not in use. Butterflies eat by extending the proboscis deep into a flower to sip nectar. Butterflies also use the proboscis to drink water and juice from rotting fruits. Source: birdsandblooms.com. Photo by Nancy Ann Hibbs
