Close-up of the Cautious fly

Cautious

Slow away and no sprinter, but built for marathons and gales, and steady through hazards.

  • Barely tires, even in a marathon
  • Shrugs off gales
  • Lowest cruising speed, wins by lasting not racing

The brain, firing

A simulated spiking brain: 293 neurons in four regions. Each region fires at a rate set by this fly's tuned dials, so a busier region means that fly leans on it harder. Illustration, not recorded data.

What each region does

  • Optic lobesactivity 55

    Sees hazards, rails and swooping hawks.

  • Antennal lobesactivity 41

    Smells lures and feels the wind.

  • Central brainactivity 64

    Weighs it all up and keeps the line.

  • Descending / motoractivity 42

    Turns the decision into turns and speed.

Skills

  • Off the line12

    How hard it goes in the opening stretch (early_pace). Bold spends its energy up front; Cautious saves it.

  • Top speed47

    Cruising drive (aggression) after the flat speed tax that high stamina costs.

  • Endurance70

    How slowly its energy drains over a long race (stamina). Low stamina visibly fades in a marathon.

  • Late kick50

    How much surge it has for the closing straight (finishing_kick).

  • Hazard recovery22

    How fast it shakes off a hit from a hazard (caution cuts the collision stun).

  • Lure resistance76

    How little food and light lures pull it off line (the inverse of distractibility).

  • Wind handling70

    How much of a gale's push it shrugs off (wind_resistance).

  • Hawk reflex55

    How strongly it dodges and bolts when a hawk swoops (fearfulness). Low means it barely reacts and even slows.

  • Steadiness50

    How clean its line is (the inverse of brain noise).
