I have a small colony of Camponotus quercicola. There is one queen, nine workers, six developed larvae (late instar), and 8 recently laid eggs, about 2 days old. Today, when taking a peek at them in their plastic hybrid nest, 4 to 6 of the adult workers appeared to be aggressively biting at and tugging upon one larva, but I wasn't observing any actual cutting. Mandibles were actively opening and closing on the larva's exoskeleton.
Is this behavior common? Do they sometimes turn on a larva to destroy it? It was really upsetting to watch, but so far I'm not seeing any damage (yet). This looks a lot more aggressive than simply cleaning and feeding the larva.
I am new to this hobby, having started with my first colony in February, so I know there's a lot to learn. This behavior today is new to me. Video is below:
