Entomology

Get close to the insect world — collect, identify, and understand it.

Speculative Biology

Invent alien life that evolves by real biological rules.

Which is right for you?

Choose Entomology if…

  • You'd happily watch a single beetle for ten minutes like other people watch TV.
  • You want an ordinary backyard to turn into a habitat full of overlooked lives.
  • Working through wing-vein counts with a hand lens sounds absorbing.

Choose Speculative Biology if…

  • You like redesigning a creature once you realize its metabolism can't work.
  • The moment a creature clicks into a coherent ecosystem is enough payoff.
  • Rabbit holes into convergent evolution and metabolic scaling sound fun.

Before you commit

Entomology

  • Handling and pinning specimens would keep you squeamish for good.
  • One wrong character sending you down the wrong key would frustrate you.
  • You want a fast hobby, not slow identification with fiddly field guides.

Speculative Biology

  • Nobody seeing the years of logic behind one drawing would deflate you.
  • You want a tangible result, not notebooks and tab-stacks of evolutionary logic.
  • Starting a design over because the biology doesn't hold would frustrate you.
