Could your bees be bringing in dandelion pollen? Orange colored pollen comes from dandelions, too. I know the main dandelion bloom is in the spring, but some blossoms can be seen throughout the summer. About three weeks ago, another beekeeper here in the southcentral Alaska region was seeing some orange pollen coming into his hive. Not a lot, but still bees were coming in with it in their baskets. Nearby the hive were some dandelions in bloom. Since we’re much farther north than Connecticut that would have put us somewhere about the same, season-wise, as early November down there in the lower 48. Don’t remember exactly where I saw it, but it seems I read not too long ago that dandelions do sometimes have a minor bloom in the fall, however I couldn’t find anything on the internet to back that up
