Giant Asian Honey Bee

Apis dorsata — the giant Asian honey bee — is the LARGEST HONEY BEE IN THE WORLD and one of the most extraordinary social bees on Earth. The species is one of about 11 species in genus Apis (the true honey bees — including the European honey bee Apis mellifera, the Asian honey bee Apis cerana, and several other Apis species). Apis dorsata is widespread across South and Southeast Asia (India, Sri Lanka, Bangladesh, Myanmar, Thailand, Vietnam, Indonesia, Philippines, southern China). Workers are 18-20 mm long (much larger than the European honey bee Apis mellifera at 12-15 mm — the giant Asian honey bee is roughly 1.5x the size of European honey bees), with the species' diagnostic features: large body size, golden-brown coloration with darker abdominal bands, and powerful flight musculature for the species' long-distance foraging behavior (Apis dorsata workers regularly forage 5+ km from the hive, much farther than European honey bees that typically forage within 2-3 km of the hive). The species is unique among honey bees in NESTING IN MASSIVE SINGLE-COMB OPEN-AIR HIVES rather than in enclosed cavities (like European honey bees, which nest in tree hollows, rock crevices, and human-made beekeeping hives) or in protected multi-comb arrangements (like Asian honey bees Apis cerana). Apis dorsata HIVES: each colony builds a SINGLE LARGE COMB (typically 1-2 m wide and 0.5-1 m tall — the size of a small dining-room table) suspended from a HORIZONTAL OVERHANGING STRUCTURE such as a cliff overhang, large tree branch, or building eave. The comb is fully exposed to the open air with no protective enclosure. Each comb contains TENS OF THOUSANDS OF BEES in a single visible cluster — typically 30,000-100,000 workers per colony. Multiple colonies often nest near each other on the same supporting structure (cliff faces in southern India and Southeast Asia can support 100+ Apis dorsata colonies on a single large overhanging cliff face — a spectacular natural phenomenon). The species is famous for the SHIMMERING DEFENSIVE WAVE behavior. When threatened by approaching predators (especially Asian hornets, see Vespa velutina and Asian giant hornet Vespa mandarinia in the Wild Files; and bird predators), HUNDREDS OF BEES on the COMB SURFACE SIMULTANEOUSLY FLIP THEIR ABDOMENS UPWARD in coordinated waves that RIPPLE ACROSS THE ENTIRE COMB SURFACE — creating a hypnotic SHIMMERING VISUAL DISPLAY that startles and confuses approaching predators. The wave behavior involves precise sub-second coordination among thousands of individual bees and is one of the most-cited examples of COLLECTIVE BEHAVIOR in modern social insect biology. The shimmering wave defense is featured in essentially every modern textbook discussion of social insect collective behavior. The species is the source of MOST OF SOUTH ASIA'S WILD HONEY — Apis dorsata combs produce 20-50 kg of honey per colony per season, and traditional honey gathering from giant Asian honey bee colonies on cliff faces is a culturally important and economically significant industry across India, Nepal, and Southeast Asia (the famous 'Honey Hunters of Nepal' and similar traditional industries depend almost entirely on Apis dorsata wild honey). The species is harmless to humans EXCEPT WHEN COLONIES ARE DISTURBED — Apis dorsata workers are highly defensive and can deliver painful stings, with mass attacks on disturbance posing serious medical risk to honey gatherers and other people approaching active colonies.
