sawfly
LowTechnical / Scientific
Definition
Meaning
An insect belonging to the suborder Symphyta, whose females have a saw-like ovipositor used to cut into plant tissue to lay eggs.
The term can also refer to the larval stage of these insects, which are often plant-eating caterpillars that can be pests in gardens and forestry.
Linguistics
Semantic Notes
The name is derived from the appearance of the female's ovipositor, not from any action of 'flying' in a saw-like manner. It is a compound noun where 'saw' refers to a tool.

The most obvious sign is damage from their larvae, which chew on leaves, often leaving only the veins (skeletonisation).
Generally, they are considered pests in horticulture and forestry. However, as part of the ecosystem, they serve as a food source for birds and other insects.
