More questions about Cordyceps

These visible examples show the question style. LearnClash turns the full topic into ranked duels and spaced repetition.

  1. 1 Easy

    Why does Cordyceps usually only infect one kind of insect?

    Answer: Strict species requirements

    Why: Lab work found the fungus answers each host species' brain with its own chemical mix, so only its natural host is fully manipulated.

  2. 2 Medium

    Which survival video game series was inspired by real Cordyceps fungi?

    Answer: The Last of Us

    Why: Neil Druckmann got the idea from a 2006 Planet Earth segment showing Cordyceps steer an ant to its death, then sprout from its head.

  3. 3 Hard

    Which season marks the start of the Himalayan Cordyceps harvesting period?

    Answer: Late spring

    Why: Snowmelt sets the start, mostly May into June, for what Tibetans call yartsa gunbu, summer grass, winter worm.

  4. 4 Easy

    What led to the discovery of Cordyceps in ancient medicine?

    Answer: Observing healthy livestock

    Why: Its Tibetan name, yartsa gunbu, means 'summer grass, winter worm', for the grass-like stalk that sprouts from a dead larva.

  5. 5 Medium

    Why does Cordyceps sinensis grow only at high altitudes?

    Answer: Its moth host lives only there

    Why: Its ghost moth host lives only in alpine meadow, and the fungus itself stalls above about 21 degrees.

  6. 6 Hard

    Why does the Cordyceps fungus utilize molecular mimicry?

    Answer: Evading host immunity

    Why: Camouflage is only half of it: Cordyceps militaris also releases cordycepin, which damps down the insect's own immune genes.
