Bagworms, Thyridopteryx ephemeraeformis, produce conspicuous spindle-shaped cocoons on trees and shrubs throughout the United States.Bagworms feed on over 128 plant species. Some bagworm species are parthenogenetic, meaning their eggs develop without male fertilization. The cases of the more primitive species are flat, while specialized species exhibit a greater variety of case size, shape, and composition.

Bagworms - Trees and Shrubs | University of Maryland Extension Since the eggs are very hard-shelled, they can pass through the bird's digestive system unharmed, promoting the spread of the species over wide areas. The adult males of most species are strong fliers with well-developed wings and feathery antennae but survive only long enough to reproduce due to underdeveloped mouthparts that prevent them from feeding.
