Honey bees at a hive entrance: one is about to land and another is fanning. Colony collapse disorder (CCD) is an abnormal phenomenon that occurs when the majority of worker bees in a honey bee colony disappear, leaving behind a queen, plenty of food, and a few nurse bees to care for the remaining immature bees.

A worker bee's waggle dance involves running through a small figure-eight pattern: a waggle run (aka waggle phase) followed by a turn to the right to circle back to the starting point (aka return phase), another waggle run, followed by a turn and circle to the left, and so on in a regular alternation between right and left turns after waggle runs.
The recent introduction of sliding 'follower boards' [12] to enclose the colony within the hive body has enabled more flexible management of top bar hives and facilitated quicker inspections with minimal disturbance to the bees. (Follower boards are adjustable solid panels, which effectively reduce the size of the interior space within the hive ...
Honey bees communicate information regarding the profitability of a food source through: rate of reversals, number of reversals, and dance duration. [5] Research indicates that the rate of reversals in the round dance is the measure of profitability that is most highly correlated to food source quality. [ 6 ]
The blackness on the bee on the right is a symptom of CBPV. Chronic bee paralysis virus (CBPV) commonly affects adult Apis mellifera honey bees and causes a chronic paralysis that can easily spread to other members of a colony. Bees infected with CBPV begin to show symptoms after 5 days and die a few days after. [1]
A dead carpenter bee Pollinator decline is the reduction in abundance of insect and other animal pollinators in many ecosystems worldwide that began being recorded at the end of the 20th century. Multiple lines of evidence exist for the reduction of wild pollinator populations at the regional level, especially within Europe and North America.
Vanishing of the Bees is a 2009 documentary film by Hive Mentality Films & Hipfuel Films, directed by George Langworthy and Maryam Henein and released in the United Kingdom in October 2009.
