''Apis dorsata laboriosa'', the Himalayan honey bee, is the world’s largest honey bee; Limited to the Himalayas, it is the largest of the ''Apis'' species. So far it has only been identified in the mountainous regions of Bhutan, the Chinese province of Yunnan, India, and Nepal. It mostly nests at altitudes between , building very large nests under overhangs on the south-western faces of vertical cliffs. One nest can contain as much as of honey. The bees forage at altitudes of up to . Due to its peculiar nesting behavior, the Himalayan honey bee is also referred to as the Himalayan cliff honey bee. The term "Himalayan honey bee" is sometimes used more informally, for any of the four varieties of honey bees that are found in the Himalayan region; ''Apis cerana'', ''Apis florea'', ''Apis dorsata'' and ''Apis dorsata laboriosa''. There are three different types of ''Apis dorsata laboriosa'' honey: spring or red honey that is collected at higher altitudes, spring honey collected at mid and lower altitudes, and autumn honey from any site. Red honey has an intoxicating effect and various relaxing qualities that decrease over storage. It is not consumed locally as it is valuable, and honey hunters prefer to sell it at a high price. As hive bees are not kept at such high altitudes, ''Apis dorsata laboriosa'' is the only bee species to produce this honey. The wholesale price of the red honey is about five times the price of regular honey from ''Apis mellifera'' or ''Apis cerana'' and large amounts of it are exported from Nepal to Japan, Korea, and Hong Kong. The red honey is prized for its purported medicinal value and intoxicating qualities which are attributed to the grayanotoxin present in the nectar collected from white rhododendrons (Rhododendron spp). The Gurung people in Nepal are renowned for their use of this mad honey, both for its medicinal and hallucinogenic properties. == References == * (2005): Phylogenetic relationships of honey bees (Hymenoptera:Apinae:Apini) inferred from nuclear and mitochondrial DNA sequence data.
