Reader Judy Brook took this picture while kayaking the LaPlatte River in Shelburne, VT. What is it?
Answer
A gypsy moth egg mass.
This dollop of fluff represents up to a thousand caterpillars, each capable of munching their way through about nine square feet of leaf area. An invasive insect that first arrived on our shores circa 1860s, the gypsy moth is particularly fond of oak and aspen, but USDA - APHIS reports that the critters will eat over 300 different species of trees and shrubs.
