Populicerus unicolor
This record describes Populicerus unicolor (species). Recorded family: Cicadellidae. Recorded order: Hemiptera.
Identification and Appearance
Hamilton (1980): Adults of unicolor closely resemble those of pallidus in habitus and male genitalia, but differ in size ( pallidus males being less than 5.4 mm long, females rarely as much as 6.2 mm long), size of the male antennal disc (Figs. 33, 34), shape and colour of the tergal apodemes (Figs. 56, 57), and length of the ovipositor (not more than one-quarter of third valvulae extending beyond pygofers in pallidus). I. unicolor appears to be generally more southern in distribution than pallidus . Adults of unicolor also closely resemble those of perplexus , but are larger, and the males have longer antennae and shorter penis processes. The type-specimens taken on Salix discolor and S. lucida are probably strays from adjacent trees.

About True Bugs, Cicadas, Hoppers, Aphids and Allies: the wider group
Order-level background for Hemiptera, the group containing Populicerus unicolor. 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.
Recorded sources for this group: USDA, EPA, University research. Imported estimates may describe particular regions or reporting periods.
