Since I have awakened my Camponotus novaeboracensis colony it has been eating it's larger larvae. I am at a lose to why they are doing this but they are doing it frequently and I am thinking that they will have eaten all the overwintered brood within a few more days if it continues. The queen has started laying and there are many eggs and a lot of small larvae. They seem to be eating only the larger larvae that were the overwintered brood that have grown since they have come out of hibernation. The nest has been heated but only on the far left edge of the nest and the nest is large enough that they are not crowed and can move to cooler parts of the nest if they would like. I keep the moisture up and they are feed daily with several crickets and anything else I can find or buy such as spiders and meal worms. They have access to sugar water daily as well. All other functions seem the same, they forage, I see them feeding the small and larger larvae, trash is taken out, etc. I am at a lose. Can any one explain this behavior? They are kept in the same conditions that they were last year and they thrived last year going from a small colony to well over 200 and perhaps bordering on 300.
