If you spot something in a tree or shrub that looks like an oddly-shaped pine cone, take a closer look.

It could be a bagworm sac ready to release an army of creepy, maggot-like larvae capable of stripping evergreen needles and tree leaves.

These adaptive insects spin cocoons suspended from tree branches, using material from the host tree to create a camouflaged, pine cone appearance.

Bagworm larvae can attack both coniferous and deciduous trees. Common evergreen hosts include hemlock, cedar, juniper, pine and spruce. The young larvae are black and shiny on top with a dull amber underside. As adults, the males develop into flying moths, while the wingless females remain hidden inside the pouch.
