Hi everyone,

I've recently noticed a cocoon type structure on a large adult Picea
Pungens and now on my new Pinus Densiflora. The cocoon seems to be
made of old and or dead needles and hangs down from the banch. It
looks rather scruffy and strange not very uniform and basically looks
like glued together needles.

Initially I passed it off as some kind of natural function of the
Picea Pungens, but this morning I noticed an identical cocoon on my
Densiflora? They are attached to the underside of the branch and might
be tapped into the sap?

Does anyone have any idea what this might be? Is it threatening to the
health of the trees?

I think it might be some kind of moth or butterfly but there are so
many, and I know so little about them that Google can't even help me.

thanks,
-Ethan
