It's a bit like being aware of a movie that was out when you were a child, you never saw it but you know you would've really loved it if you had.
Well, I'm glad to finally find out some more about this formidable, aerial predator. And I must say, I'm impressed!.
Robber Flies are some 7,000 species of true fly in the family Asilidae. They're found all over the world, and range in size from half a centimetre or so (about 0.2 inches) to about 5 cm (2 in) long.
Most look hunchbacked, with their head attached halfway down a large thorax. They also tend to have a long, slim abdomen, though others are much thicker-bodied and are remarkable mimics of wasps or bees.
The main thing, though... the real "Robber Fly" thing... is their amiable lust for killing.
It must be tactics like that which earned them the codename Assassin Fly. It appears that the main thing they rob is life or souls or something, so at least your jewellery is safe.
Scanning the skies because SOMETHING MUST DIE!
You will often find Robber Flies hanging out on the ground or on logs or plants during the hottest part of the day. They scan the skies above them, their head-dominating eyes alert for the sight of flesh on the wing.
With prey spotted, the Robber takes to the air and gives chase. Their muscles, freshly warmed by the Sun's heat, allows them to outpace their mark.
The Robber plucks its victim from the air with long, thick legs and returns to its perch. Long, pointed mouthparts seek out a weak spot in the struggling bundle of exoskeleton. Enzymes are injected, some to paralyse, others to liquefy innards.
SOMETHING HAS DIED!
Soon, the struggle is over as a life breaks down into its constituent sludge.
In fact, the whole thing is like a flying spider. The Wizard of Oz may have missed a trick.
Larval Robber Flies are maggots that live in dark, moist areas like soil, logs and decay. Like their parents they are voracious predators, this time on eggs and the soft bodied larvae of other insects.
But, while the adults so clearly dominate their domain, the youth are largely shrouded in mystery.
But not for long
Soon these worms will attain their shimmering wings of glorious death. Stepping out of the shadows, the time to bring horror to the sunny uplands has come...
