Bee Buzz Box July 2022 Giant Honey Bees Part I – The Sting is in the Tail

Site of fossil Apis lithohermaea Iki Island Japan

Alan Wade

The Apis dorsata group are the whoppers of the bee kingdom: they have the largest body mass, the longest and largest stings, by far the largest venom glands and, to boot, one extra sting barb. They are also exceptionally aggressive and have distinctive behaviours that ward off the most unwelcome intruder. This accords them the status of being the most savage insect on earth.

It is also instructive to reflect that these giant bees have been around for a long time having a lineage that dates back to the Mid Miocene (Figures 1 and 2). That was some 14-16 million years ago and that was way before primitive forms of Homo sapiens first appeared just 300,000 ybp.

Enigmatic giant honey bees

Charles Michener’s Bees of the Worldii lists one hundred and thirty eight scientific names for honey bees. While some are well known to palaeontologists many are extinct. However the majority are simply old names for the ten or maybe twelve different honey bees currently recognised (Table 1).

Table 1 Extant (existing) honey bees
*On the basis of detailed morphometric measurements Apis nuluensis, found at high elevation (1500-3400 m) in Sabah, has sometimes been accorded separate species statusiii.

Giant honey bees are widespread in India and Asia but do not extend eastward to Timor, Irian Jaya, Papua New Guinea or to the Pacific (Figure 3).

Figure 3 Geographic range of the giant honey bees of the Apis dorsata groupiv

Until relatively recently there was thought to be a single extant giant honey bee, Apis dorsata. It isspread right across the tropical Indian and Asian subcontinents. There are now known to be a total of three, perhaps four, different species of giant honey bee. First to be recognised as a new species was the Himalayan Cliff Honey Bee or Giant Mountain Honey Bee, Apis laboriosa. It is well recognised for its adaptation to seasonal nesting and foraging of summer flora to altitudes up to 4000 m and for its being the largest of all honey bees (Table 2). Then have come more recent genetic studies that has accorded the long isolated Giant Philippine Honey Bee, Apis breviligula, separate species statusv. On the back burner is the also isolated Giant Sulawesi Honey Bee, Apis dorsata binghami. It, like the other two species and Asian mainland Apis dorsata, has different abdomen and stripe patterning but its genetic makeup is not sufficiently clear to determine whether it, too, has been isolated long enough to give it separate species status.

Size estimates vary by region: for example Chinese populations of giant honey bee species reportxiii smaller length by width forewing measurements for Apis dorsata 12.8 x 4.3 mm and for Apis laboriosa 13.6×4.5 mm

Other defining features of the giant honey bees are evident at the colony (super organism) level (Table 3) though there are few published studies on the nest and colony characteristics of the giant Sulawesi and Philippine honey bees.

**Studies of the biology of the Giant Philippine Honey Bee, Apis breviligula and the Giant honey bee of the Sulawesi, Apis dorsata binghami are few though their biology appears similar to that of widespread Apis d. dorsata: Both commonly nest in tall trees, but A. d. binghami is less likely to aggregate in large numbers in trees (several to ten for A. d. binghami and up to around one hundred for Apis d. dorsata)xvi
***Apis mellifera colonies are larger and less numerous per square kilometre in Europe than those found in Africa

Overall the giant honey bees are becoming more widespread in the tropics but are absent from Central America, the Pacific Islands, Australia, New Zealand, Irian Jaya and from Papua New Guinea. The giant honey bees are the natural hosts of parasitic mites belonging to the genus Tropilaelapsxviii.

The most defining feature of the different members of the ‘Apis dorsata group’ is that they are geographically separated, where allopatric speciation, genetic drift due to long isolation, has occurred. The overall picture is one of the large geographic range of Apis dorsata (Apis dorsata dorsata) and island occupation by the variants (Figure 4).

County distribution and association with co-evolved Tropilaelaps parasites is shown below (Table 4).

Table 4 Distribution of giant honey bees and associated Tropilaelaps parasites
*Apis dorsata also hosts the external parasites Acarapis externus and Acarapis dorsalis but their origin is uncertain as they also impact on Apis cerana and introduced Apis mellifera. A externus is found in Australia but is not accorded pest status.
#Apis dorsata has spread east to Kenya and Afghanistan, so may be spreading elsewhere in the Near East.

There is a limited literature on giant honey bee pheromones. We know that Nasonov glands of giant honey bees produce alarm pheromones. In the cavity dwelling Apis sub genus, they function primarily to facilitate bee aggregation, for example forming part of the glue that keeps swarming bees together and that assists bees in orienting themselves at colony entrances.

In a study conducted by Shearer and coworkers, we learn that principle component of queen substance, 9-oxodec-trans-2-enoic acid – we might call it hive glue – is produced in comparable quantities by Apis dorsata, Apis cerana and Apis melliferaxxi queens. This and associated queen mandibular gland pheromones are inimical to the cohesion and functioning of the brood nest and functions in other ways in maintaining colony homeostasis: the roles of queen substance are as disparate as control of drone comb and queen cell construction, control over the production of both supersedure and swarm queens and for queen retinue and swarm cohesion.

The self-assembly processes in honey bees is easily recognised in phenomena such as swarming and when bees cluster together when they are dislodged from frames and capacity to coordinate defence activities in response to hive invasion by predators. Yet the range of behaviours differs distinctly between dwarf, cavity nesting and giant honey bees well illustrated in the disparate strategies for colony self defence adopted by the different honey bee groups.

Colony defence

Apiaries comprising domesticated western and Asian honey bees – European and a few South African races of Apis mellifera and Japanese and Chinese races of Apis cerana – are afforded a large measure of protection by the hive we provide them. All wild colonies of cavity dwelling honey bees gain further protection from more study and better insulated hollows, from their proclivity to employ small defendable colony entrances and from some behavioural traits, notably Asian honey bees heat balling insect predators.

To varying degree all honey bees employ stinging to fend off vertebrate predators (bears, mice, people, skunks, gophers…), their venom having much the same potency across all species. However the amount of venom they can deliver and their proclivity to sting varies widely.

The dwarf honey bees employ strategies such as camouflage (hiding nests in leafy undergrowth), applying sticky exudates to branch attachment to repel ants and retreat and readily abscond in response to wholesale predation. Giant honey bee nests, on the other hand, are in the open and quite conspicuous, though typically inaccessible. They build their nests high in large trees (Figure 5) or attach their singe comb to rock overhangs and have a lethal sting apparatus (Table 5).

This all said the giant honey bee defence lies as much in their large sting and venom apparatus but also in their aggression behaviour. This makes the giant honey bees such dangerous animals.

Jerzy Woyke and coworkersxxii in assessing the best way to handle giant honey bees noted that:

The extraordinary defense behavior of Apis dorsata is well known. Roepke (1930)xxiii described an A. dorsata attack, during which the worker bees followed him for 500 m. When Lindauer (1956)xxiv was attacked, the bees followed him for 2 km. Near Anuradhapura, Sri Lanka, three water buffalos were killed by A. dorsata. According to Morse and Laigo (1969) [loc. cit] there is no question that this is the most ferocious stinging insect on earth.

Open nesting bees – both the dwarf and giant bees form a protective barrier at their point of attachment to the substate effectively removing the risk of predation by ants. Other behaviours such as hissing and extending the size of the curtain and bees shimmering, the latter two particularly pronounced in the giant honey bees, are effective in preventing attack by predatory insects such as waspsxxv.

Table 5 Defence characteristics of representative honey bee speciesxxvi

One detail of a behavioural trait in both the Giant Honey Bee and in the Giant Philippine Honey Bee is upward abdomen flipping (the aforementioned shimmering) captured on camera by Kastberger, Weihmann, Zierler and Hötzlxxvii. This behavioural trait helps regulate brood nest temperature of the bee curtain protecting the open nest and would appear effective in warding off wasp predators. Much recommended is viewing of the Kasterberger short video clips demonstrating dorso-ventral abdomen flipping response of Apis dorsata colony to wasps1.


To conclude our introduction to these giant bees there is of course a long history of their association with human settlement in southern Asia and the problems they present. A favourite childhood recollection of the strife these creatures inflict is told in the Red Dog yard spun by Rudyard Kipling in his second jungle bookxxviii.

A cautionary tale

When marauding hordes of the Red Hunting Dog (Dholexxix), Cuon alpinus, of the Deccan Plateau descended from the Seeonee Hills they did not reckon on the fearsome giant honey bee (Apis dorsata) festooning the cliffs of the Northern Indian Waingunga River Gorge:

The split and weatherworn rocks of the gorge of the Waingunga had been used since the beginning of the Jungle by the Little People of the Rocks—the busy, furious, black wild bees of India; and, as Mowgli knew well, all trails turned off half a mile before they reached the gorge. For centuries the Little People had hived and swarmed from cleft to cleft, and swarmed again, staining the white marble with stale honey, and made their combs tall and deep in the dark of the inner caves, where neither man nor beast nor fire nor water had ever touched them. The length of the gorge on both sides was hung as it were with black shimmery velvet curtains, and Mowgli sank as he looked, for those were the clotted millions of the sleeping bees…

As he listened he heard more than once the rustle and slide of a honey-loaded comb turning over or falling away somewhere in the dark galleries; then a booming of angry wings, and the sullen drip, drip, drip, of the wasted honey, guttering along till it lipped over some ledge in the open air and sluggishly trickled down on the twigs.

The pursuing Red Dog pack, led by Mowgli, plunged into the gorge:

Overhead they could hear furious short yells that were drowned in a roar like breakers—the roar of the wings of the Little People of the Rocks. Some of the dholes, too, had fallen into the gullies that communicated with the underground caves, and there choked and fought and snapped among the tumbled honeycombs, and at last, borne up, even when they were dead, on the heaving waves of bees beneath them, shot out of some hole in the river-face, to roll over on the black rubbish-heaps.

In the next episode, Part II, we will track the biology of each of the giant-honey bees those thrown up by the complex biogeography of the South China Sea and South Asian mainland. This region is the cauldron of evolution of not only the giant honey bees but also of all honey beesxxx.
