Casu Marzu (food for island monkeys)

I'm just going to preface this with, what the fuck is wrong with people? no, i don't have anything smart or funny to say about, just wtf, i'm dumbfounded. this is what happens when you leave people on islands, people.


cut and paste job from wiki: https://en.wikipedia.org/wiki/Casu_marzu

Casu marzu, transliterated into English as "rotten/putrid cheese", is a traditional Sardinian sheep milk cheese that contains live insect larvae. Although from the island of Sardinia, a variety of this cheese is also found on the nearby island of Corsica, where it goes by the name of casgiu merzu.

Derived from pecorino, casu marzu goes above and beyond typical fermentation to a stage of decomposition, brought about by the digestive action of the larvae of the cheese fly Piophila casei. These larvae are deliberately introduced to the cheese, promoting an advanced level of fermentation and breaking down of the cheese's fats. The texture of the cheese becomes very soft, with some liquid (called lagrima, Sardinian for "teardrop") seeping out. The larvae themselves appear as translucent white worms, about 8 mm (0.3 in) long. When disturbed, the larvae can launch themselves for distances up to 15 cm (6 in).

Casu marzu is created by leaving whole pecorino cheeses outside with part of the rind removed to allow the eggs of the cheese fly Piophila casei to be laid in the cheese. A female P. casei can lay more than 500 eggs at one time. The eggs hatch and the larvae begin to eat through the cheese. The acid from the maggots' digestive system breaks down the cheese's fats, making the texture of the cheese very soft; by the time it is ready for consumption, a typical casu marzu will contain thousands of these maggots.

Casu marzu is considered by Sardinian aficionados to be unsafe to eat when the maggots in the cheese have died. Because of this, only cheese in which the maggots are still alive is usually eaten, although allowances are made for cheese that has been refrigerated, which can kill the maggots. When the cheese has fermented enough, it is often cut into thin strips and spread on moistened Sardinian flatbread (pane carasau), to be served with a strong red wine. Casu marzu is believed to be an aphrodisiac by Sardinians. Because the larvae in the cheese can launch themselves for distances up to 15 centimetres (6 in) when disturbed, diners hold their hands above the sandwich to prevent the maggots from leaping. Some who eat the cheese prefer not to ingest the maggots. Those who do wish to eat them place the cheese in a sealed paper bag. The maggots, starved for oxygen, writhe and jump in the bag, creating a "pitter-patter" sound. When the sounds subside, the maggots are dead and the cheese can be eaten.

Emerald Jewel Wasp

Cockroaches can fall victim to the parasitoid Jewel Wasp (Ampulex compressa), which employs them as live, yet immobile food supply for its larva. Unlike most other parasitoids, this tropical Ampulicine wasp does not simply paralyze its prey to immobilize it. Instead, it stings a cockroach in the head and injects a neurotoxic venom cocktail directly inside the cerebral ganglia. This turns the cockroach, metaphorically, into a submissive ‘zombie’: it gradually enters a long-lasting hypokinetic state, during which it becomes unresponsive to aversive stimuli and fails to self-initiate walking or escape behaviors. Although the stung cockroach is not paralyzed, it allows the wasp to cut both its antennae and drink hemolymph from the cut ends. The wasp then grabs one of the antennal stumps and pulls backwards, leading its prey into a pre-selected nest. The intoxicated cockroach, rather than fighting or fleeing its predator, actually follows the wasp submissively. In doing so it demonstrates a completely normal walking pattern, as if it was a dog led by his Master's leash. The wasp then lays one egg on the cockroach's leg, seals the nest and leaves the lethargic prey inside, still alive but powerless to escape under the influence of the venom. As the wasp larva hatches from the egg, it penetrates through the cockroach's cuticle and feeds on its internal organs for several more days. Only then, roughly five days after the sting, does the cockroach finally die and the larva pupates inside its abdomen, safe from predators outside the nest.
