Cane toads just can’t catch a break

cane-toad-2

Once upon a time, 101 Cane toads were  deliberately introduced to Australia, under the premise that they would eat the beetles ruining the sugar cane crops, ridding the farmers and population of a costly pest. Yet as we have learned time and again, the road to hell is paved with non-native species.  The population of poisonous cane toads exploded in Australia, the toxic toads started causing deaths of native species, and a variety of measures were sought to mitigate the new-and more obtrusive- problem, including:

1) Golf clubs (the author of BV cannot reccomend this, though she does understand the sentiment)

2)freezing 

3) gassing

 

But now, scientists believe that they may have found “a more natural way” to kill these killers: Meat ants.

…Yes folkes, this is another one of *those* posts.

Meat ants, a carnivorous species native to Australia,  have been observed eating cane toadlets, leaping upon them and devouring them alive. Or dead, however they find them.  Unlike the native toad species, moreover, the cane toads have not evolved defences to meat ants as have their Aussie counterparts. Simply put, “they do not hop away.”

Not one to hook his wagon to just any star, the mayor of Darwin and Frogwatch coordinator, Graeme Sawyer doubts that these ants can come to the rescue, as they “just don’t eat enough toads.”

Who knows whether sending the toads to swallow the beetles, and sending the ants to swallow the toads will end in tragedy… But the author of BV is put in mind of a childhood song …

Hercules Beetle: natural prey of the Stymphalian birds?*

behold the strongest insect on earth (and in the background, the much smaller flower beetle).

 The Hercules beetle (Dynastes hercules) is perhaps the most immediately recognizable of the rhinoceros beetles; it’s propensity for epic battles and family tragedies in the Grecian vein, though less well known, is among the beetle’s most prominent characteristics. 

Male beetles, for instance,  often use their prominent horns to fight for the right to mate with a comely female. The outcomes of these battles are determined by the whims of the gods, and may inflict devastating psychosocial effects which can fatally disrupt the entire Dynastes  family.

The winner and his prize may then engage in extended bouts of celebratory lovemaking; amorous sessions between Hercules beetles can last for 50 minutes-considerably longer than the average human encounter, which clocks in at a whopping… two minutes.

Epic, indeed.
