Hundreds, maybe thousands, of these moth larvae are making their cocoons at the expense of our neighbors conifer shrub. They surround themselves with a sticky string that they secrete and then the needles are stuck and woven to that soft inner case. I wish a picture could capture the creaky, scratchy sound that from a distance this bush seemed to make-hundreds of caterpillars slowing stretching out of their cocoons, inching forward or falling to the ground, and then dragging the cocoons back towards their head. Spectacular and a little creepy.
What looks like a Christmas tree in January...needles brown and hanging limply...is actually a site of metamorphosis for these caterpillars, destined to become moths, who, for a couple of weeks, are calling these dead needles 'home'.
