Sawfly larvae possess what distinguishing eye feature compared to Lepidoptera larvae?

Explanation:
Sawfly larvae differ from caterpillars in their eye structure, which is a helpful diagnostic feature. They have a single compound eye, whereas Lepidoptera larvae (caterpillars) possess multiple simple eyes (stemmata) along the head. A compound eye is built from many facets and provides broad motion detection, while the simple eyes sense light intensity and basic visual cues. This contrast reflects their different evolutionary lineages and visual needs.
