Did you know that weaver ants will use the empty cocoons from silk moths as founding nests? (source)
Pretty cute! Could be a good nest idea for those who try to keep weavers. Better than trying to keep them in fresh leaves...
Camponotus pennslyvanicus eats the silk cases not long after a new ant emerges. Though I have seen them in the garbage pile from time to time.
Lasius neoniger? I have no idea what they do with silk cocoons. Despite having filmed the queen laying eggs, and cocoons being spun, I have never managed to catch one of these ants emerging... or seen what happens to the cocoons. Have any of you noticed?
I've also noticed that some ants save used cocoon in a pile in the nest. I was distressed by this, thinking it was a trash pile in the nest, but I've noticed that when they don't have a bug to much on the workers will grab a cocoon and wander around chewing on it. Is this some kind of shelf-stable snack food?
What do your workers do with old silk?
