Which genus typically includes the notorious Woolly Apple Aphid (*Eriosoma lanigerum*)?
Answer
*Eriosoma*
The term 'woolly aphid' is commonly used to designate species belonging to the *Eriosoma* genus, with the Woolly Apple Aphid (*Eriosoma lanigerum*) being a prime example. This classification separates them, though visually similar due to wax secretion, from related insects such as the Woolly Alder Aphid (*Prociphilus tessellatus*). While both groups share the characteristic flocculent wax covering, their specific host dependencies and progression through their life cycles often reveal specialized evolutionary divergence. The distinction between these genera highlights how morphology can sometimes mask underlying differences in ecological specialization and life cycle execution.
