Zombie fly fungus lures healthy male flies to mate with female corpses (2022) (phys.org)

> "We see that the longer a female fly has been dead, the more alluring it becomes to males. This is because the number of fungal spores increases with time, which enhances the seductive fragrances," explains Henrik H. De Fine Licht

He’s a Licht! It says so right there!


That name is a little on the nose.


How so? German/Dutch licht should correspond to modern English light, and this is indeed the case:

> From Middle High German liecht, from Old High German lioht, from Proto-West Germanic *leuht, from Proto-Germanic *leuhtaz, from Proto-Indo-European *lewk-. Compare Dutch licht, English light.

> light, bright (luminescent)

> unobstructed, clear

(The Dutch word, like the English word, also means "the opposite of heavy".)

( https://en.wiktionary.org/wiki/licht#Etymology )

Lich comes from Old English lic, a completely different kind of word form. [The Old English form suggested by light is liht, but in fact the OE word is leoht.]

It is unrelated to light; instead, the more common descendant of lic in modern English is the word like.


It’s a fantasy reference I believe. https://en.m.wikipedia.org/wiki/Lich


It has an Old English etymology of death and cemeteries, cf. lichgate


Lich does. Light doesn't.


Yes, it just turns into a kind of funny pun across languages.

“De Fine Licht” in English looks like a funny spelling of “The Fine Lich,” like we’re describing a good looking undead wizard. False cognates lead to funny coincidences.


explain?


I think they refer to Lich. From wikipedia: In fantasy fiction, a lich (/ˈlɪtʃ/;[1] from the Old English līċ, meaning "corpse") is a type of undead creature. https://en.m.wikipedia.org/wiki/Lich


Let me get this straight: you find a fungus that can take over creatures, turn them into zombies, kill then, then make more creatures copulate with a corpse to spread the fungus and you are recommending we put that stuff next to our homes and food facilities?


Adding necrophilia to my zombie apocalypse bingo card as we speak


Better yet, there are already highly effective fly traps that use chemical scents, why do we need zombie fungus traps.


A bit hard to see what the problem is here.


probably will be a canned tea sold at whole foods soon

seeing that cordyceps is distributed this way, I think it could be seen as a deliberate reproductive strategy


The hormone, not the fungus


There are so many examples in the insect world of mind control its truly bizarre.

The other day I encountered an example in David Goulson's recent book Silent Earth (https://www.goodreads.com/book/show/56470413-silent-earth) that I did not know yet about; the emerald cockroach wasp (ampulex compressa).

Rough transcription; for its reproduction, the wasp injects a cockroach with poison to paralyze it, then stings it in exactly that part of the brain responsible for its flight reflex to make it docile. After knibbling a bit on the cockroach's antennae and enjoying the hemolymph seeping out of the cockrach, the wasp takes the cockroach by its antennae and, even though it is much bigger than the wasp, directs it to its nest like a dog on a leech. In the nest of the cockroach the wasp lays an egg, which soon hatches a larvae that in turn proceeds to eat the cockroach alive while it is still dazed...And this is just the top of the ice berg.


What are exact species? This sounds made up.


The world at the scale of insects is truly brutal.


Because the world at our scale is a walk in the park.


unironically yes


[flagged]


> astonishingly high rate of such infection in ... community

I wonder what kind of parasites and infections drive bigotry, ignorance and general unpleasantness.

Well, this will certainly be an interesting plot device in The Last of Us.


This reminds me of the Psirens episode from Red Dwarf:

https://en.m.wikipedia.org/wiki/Psirens


> As male flies copulate with dead females, the fungal spores are showered onto the males, who then suffer the same gruesome fate

Does it lure females to copulate with the male corpses? Or males?


The pheromones usually work in one direction. Otherwise female flies would also be attracted to other females. Also males seem to prefer infected females only [1]:

> Housefly males are able to distinguish between male and female cadavers also when covered in infectious E. muscae conidia, and appear to readily initiate courtship and mating strikes towards infected female cadavers.

[1] https://www.nature.com/articles/s41396-022-01284-x


Then how does the cycle close? Does it spread from males through females without any behaviour modification?


my question too, so the males are just bad at spreading it?

or maybe they mate often enough to spread it to more females


There is a scifi novel from the 80s or 90s employing a ~somewhat~ similar plot device for a human, although the name now escapes me. Ring a bell with anyone?


Would be great if we could somehow use this mechanism to kill ticks as well.


Sounds like the perfect incel cure.
