Penny Harris of Cambridge, Vermont took this photo of a pine branch near her home. What’s protruding from the branches?
Answer
Cecropia Moth Cocoon.
This is the cocoon of a cecropia moth (Hyalophora cecropia) – the largest native moth in North America with a wingspan of 5 to 6 inches. As a caterpillar, the cecropia feeds on various shrubs and plants, and spins a cocoon of brown silk. As a moth, the cecropia flies mostly at night, and does not eat at all: it lives merely a few weeks, and its sole purpose is to mate.
Incorrect but creative answers included a praying mantis cocoon and mistletoe.
