IPA: /ˈsɔːflaɪ/
KK: /sɔːflaɪ/
A type of insect that belongs to a group known for having a saw-like tool for laying eggs in plants. The larvae often look like caterpillars and feed on plants.
The sawfly larvae were eating the leaves of the garden plants.
The word 'sawfly' is formed from 'saw' (from Old English 'sagu', meaning a tool for cutting) and 'fly' (from Old English 'flēoge', meaning an insect that flies). A sawfly is an insect that has a saw-like ovipositor used for cutting into plants to lay eggs.
Think of a tool that 'cuts' ('saw') and an insect that 'flies' — that's how a sawfly gets its name, as it uses a cutting tool to lay its eggs.
