How Native Speakers Use Gusano
Real example sentences across three contexts you'll actually run into.
Finding a worm in food

The fruit had a worm inside and I had to throw it away.
Gusano is the default word when a larva or worm appears in food.
Gardening with earthworms

Earthworms improve the quality of garden soil.
Lombriz (plural: lombrices) is standard in agriculture and composting conversations.
Talking about a caterpillar
Esa oruga verde se va a convertir en mariposa.

Oruga is distinct from gusano — it specifically refers to the larval stage of butterflies and moths.
Avoid These Mistakes When Using Gusano
Using gusano for earthworm in a science context
Incorrect: Los gusanos de tierra airean el suelo.
Correct: Las lombrices de tierra airean el suelo.
While gusano is understood broadly, lombriz (or lombriz de tierra) is the precise term for earthworms. In biology, gardening, or composting discussions, lombriz is expected.
Calling a caterpillar a gusano
Incorrect: Mira ese gusano en la hoja, va a ser mariposa.
Correct: Mira esa oruga en la hoja, va a ser mariposa.
Gusano implies a worm or larva that stays a worm. If the creature will become a butterfly or moth, the correct word is oruga (caterpillar).
