Plocamaphis flocculosa
Large Waxy Willow Aphid
Plocamaphis flocculosa is a large aphid species known for its conspicuous waxy covering. It is specialized on willows (Salix species) and produces dense flocculent wax secretions that give it a distinctive woolly appearance. The species is native to North America and has been introduced to parts of Europe, where it has established populations. Its common name directly references the characteristic waxy filaments that coat the body.
