So cold today! The baby phoebes were supposed to be out learning how to fly and catch insects, but after a few tries, they cuddled up on the fence instead. Most of the students in my butterfly class showed up in spite of the cold. We didn't see many insects. We did see a few young pipevine swallowtail caterpillars. We looked at all the plants in the butterfly garden at Tilden, and Andy talked about them. After about an hour the class left and Andy and I went for a walk. It was lovely, but cold.
