Morphology
The compound meaning is directly derivable from 'sulfur' (a yellow substance) + 'butterfly' (the insect), so a learner who knows both words can infer it refers to a yellow/orange butterfly. This color+animal naming pattern is cross-linguistically common and follows transparent compositional morphology, making the expression predictable for B1 learners.
Etymology
Sulfur butterfly gets its name from the bright yellow color of the insect because people thought it looked like the yellow substance sulfur. That's why the name means 'a yellow or orange butterfly'.
