What characteristic feature gives woolly aphids their name?
Answer
White, waxy filament secreted by the insect.
The defining characteristic of woolly aphids is the protective covering they secrete themselves, which is described as a white, waxy filament. This material gives them a distinctive, cottony appearance, leading directly to their common name. This filament is integral to their survival, serving as an armor against external threats and environmental factors, mimicking bits of lint clinging to the plant surfaces.
