I found these weird barnacle-looking things on a line for our hammock. Each little pod is about the size of a sunflower seed and the whole strand is firmly attached to the rope somehow. Some look like they've "opened" up, others are still shut. The hammock was rolled up and in the garage all winter until last weekend, so I'm not sure if these are indoor or outdoor critters.
Any ideas of what these are? Thanks for any help!
