Pemphigus populi
This record describes Pemphigus populi (species). Recorded family: Aphididae. Recorded order: Hemiptera.
Identification and Appearance
The aphid Pemphigus populi causes a green or greenish-yellow club-shaped gall to form on the leaves of Black Poplar and its hybrids such as Lombardy Poplar. The gall is found close to the base of the leaf. Mature Pemphigus populi alatae are greyish green with abundant wax. For extra information follow the ‘Further info:’ link below. If recording the gall, please provide photographs and state the host plant. If aphids are present within the gall, please also include images to show them. The position of the gall on the leaf is important when recording this species. Galls may be noted where the host trees are found. Galls may be found when the host trees are in leaf. True status in Britain is difficult to determine due to lack of records. https://influentialpoints.com/Gallery/Pemphigus_populi_club-shaped_poplar-gall_aphid.htm No additional images available for this species.

About True Bugs, Cicadas, Hoppers, Aphids and Allies: the wider group
Order-level background for Hemiptera, the group containing Pemphigus populi. Species-specific details appear above.
Group overview
Hemiptera (true bugs) includes over 80,000 described species across cicadas, aphids, leafhoppers, shield bugs, and bed bugs. Aphids alone cost global agriculture an estimated $2.5 billion annually in crop losses.
Ecological role of the group
Many Hemiptera are essential food sources for birds and predatory insects. Cicadas provide massive nutrient pulses during emergence events - a single Brood X emergence can involve trillions of individuals across 15 states.
Economic and practical significance of the group
The brown marmorated stink bug (Halyomorpha halys) caused $37 million in apple crop losses in a single year in the U.S. Mid-Atlantic region. Bed bug infestations in the U.S. increased by 500% between 2001-2010, costing the hotel industry hundreds of millions annually.
