Graphocephala coccinea is a meadow and woodland-dwelling species of brightly colored leafhopper native to North and Central America, from Canada south to Panama. Common names include candy-striped leafhopper, red-banded leafhopper, scarlet-and-green leafhopper, red-and-blue leafhopper, and sharpshooter.
Adults measure 6.7–8.4 mm in length and have vivid blue (or green) and red (or orange-red) stripes on their wings and the top of their thorax combined with bright yellow coloration on their head, legs, abdomen, and elsewhere.
Leafhoppers feed on plant sap with the aid of specialized mouthparts. G. coccinea has been identified as one of several leafhopper species that is a vector in leaf scorch caused by the gammaproteobacteria Xylella fastidiosa ("Pierce's disease"). X. fastidiosa is responsible for the decline of certain woody plants such as elm, oak, and other ornamental trees. According to a research entomologist at the United States National Arboretum, "An understanding of the transmission of this bacterium by insect vectors is economically important because there is neither any known effective therapy for infected trees and shrubs nor a strategy for preventing...

Rare
Under 5% of wildlife watchers report a Red-Banded Leafhopper sighting in Portland on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 358th most-seen of the 507 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
September
In that month about 10% of wildlife watchers report a Red-Banded Leafhopper in Portland on a given day, against under 5% in October to August, the lowest months. That is one of Portland's driest months, with about 55 mm of rain against 250 mm in December.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Red-Banded Leafhopper sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
17th of 17
Of the 17 cities where we can rate Red-Banded Leafhopper sightings, Portland ranks 17th at under 5%. The best odds are in Detroit (United States, about 20%), Boston (United States, about 20%) and Minneapolis [Saint Paul] (United States, about 10%).
Same genus: Graphocephala
The closest relatives of the Red-Banded Leafhopper that you can see in Portland (genus Graphocephala) are Rhododendron Leafhopper (about 10%) and Blue-Green Sharpshooter (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Red-Banded Leafhopper is recorded against all the insects logged in Portland (9 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
