Did you find out what they are? Are you holding 3 of the “wood looking insects” in this photo?
It occurred to me that maybe these are Bagworms — they are caterpillars that build a hiding place out of sticks, bark, bits of lichen and leaves glued together with silk. They come out and nibble, then go back and sleep in the papoose and rebuild them as they grow. These look pretty small — by the time they are full-size, Bagworm cocoons can be 1-1/2 to 1-3/4 inches long depending on materials used.
Learning never ends because we can share what we've learned. And in sharing our collective experiences, we gain deeper understanding of what we learned.
