For the first meter ever , scientists have observed interspecies war in bee — a spectacular innate phenomenon involving prolonged aerial battles and kamikaze plan of attack that lead in thousands of fatalities in both attack and defending colonies .
War is not uncommon among animals of different species ( especiallyants ) , but what is uncommon are scrap to the death . Evolutionary possibility suggests this is the case because alternative strategies that allow beast to assess strength and fighting power , like physical display , have emerged to have them avoid this costly behavior ; the hazard of death has to be outweighed by the benefits of obtaining the resourcefulness that ’s being contend , whether it be food , mates , or nesting sites .

War of Attrition
But it appear that evolution has guided a certain metal money of stingless sugarbag bee , Tetragonula hockingsi , into adopting a rather bellicose scheme in which warfare is waged against a related coinage , Etragonula carbonaria , to gain unhindered access to a coveted honey - fill hive .
research worker from Queensland University of Technology in Brisbane discover that the invading bees use their jaw as lethal weapons in an effort to permanently move out the inhabitants of a targeted hive and install their own queen mole rat to predominate . As detect by behavioral ecologist Paul Cunningham , the bee arrive in a drove and clash jaws , shut away the defenders in a “ demise grip ” with their warm mandibles .
outstandingly , endurance is not the intention of the individual attackers ; this is a classic example of a hive mentality at oeuvre — a superorganism that places the well - being of the collective forward of single members .
“ Neither the attacker nor defender pull through in these one - on - one death battles , during which a carpet of dead and dying bees can be seen on the ground . It is a bluff routine game as to who wins , ” observe Cunningham in a instruction . “ It charter three consecutive approach over several weeks before the hockingsi bees won out . When they finally break through the defences , they put out the hive in a huge swarm , mercilessly ejecting the nonmigratory workers , drones and young tabby . It was mass murder ! ”
Invaders From the North
When the research worker first discovered the phenomenon , they had been expecting to find two dependency of the same mintage at war , but that was n’t the vitrine . The lash out mintage seem to be coming into the Brisbane region from the north .
After the first fight , the invading bees back off to regroup . But about a month later they render with devastating issue . They broke through the defence and sent workers into the beehive to drag the young and inexperienced out of the beehive to dispose them . The third attacking wafture demonstrate to be the coup de grâce . The lash out swarm overwhelmed the withstander , who managed to see a girl queen into the beehive to rule .
After the hive settled and down and there was no further fight for several month , the researchers conducted a transmitted psychoanalysis on the victorious bees . Results express that a raw queen was in mansion and that she was indeed the girl of the lash out dependency ’s tabby .
Since that initial case , the researchers have study more than 250 hives around Brisbane and find grounds of 46 of these all - or - nothing takeovers over five years . This was not an isolated incident .
Andi interestingly , the hockingsi bees are not always the winners .
The researchers are n’t entirely sure why the attacks happen , but it ’s likely a effort for literal estate .
“ We still have many doubtfulness to reply , such as what instigates the attacks , and whether the young in the usurped hive are spare and reared as slaves , or kill outright , ” added Cunningham .
