Avoid These Mistakes When Using Oruga

Using gusano when you mean caterpillar

Incorrect: El gusano se va a convertir en mariposa.

Correct: La oruga se va a convertir en mariposa.

Gusano means worm or grub. While colloquially used for caterpillars, it is imprecise. Only orugas metamorphose into butterflies or moths.

Assigning masculine gender to oruga

Incorrect: Encontré un oruga enorme en el jardín.

Correct: Encontré una oruga enorme en el jardín.

Oruga is feminine (la oruga, una oruga) despite ending in -a being the expected feminine marker — some learners second-guess it because the creature may seem unfamiliar.
