Symptoms Of Colony Collapse Disorder
According to the book A Spring Without Bees by Michael Schacker the symptoms of CCD or of a hive on the verge of collapse are few adult bees and no dead bees in or around the hive; there was still no hatched brood in the hive, honey and pollen was left by the hive so other bee's wouldn't steal it; there's not enough worker bees to sustain the brood, the worker bees were primarily young adult bees and not good foragers; the queen had not flown off and was still in the hive; the remaining hive would not feed even when artificial syrup and protein supplements were provided; and finally but most suspicious weeks would pass before predators like wax moths an hive beetles would come and try to eat the wax. If you look at the second symptom and the last symptom, they both talk about how the other bees wouldn't steal what was left or how insects like the hive beetles, wouldn't come and eat what was left until weeks passed. This would mean that the other could be sensing something that humans have yet to notice.
