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...

Possible
About 20% of wildlife watchers report a Red-Banded Leafhopper sighting in Detroit on a given day, based on 78 verified sightings from GBIF citizen-science data. It is the 17th most-seen of the 268 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
June and August
In those months about 30% of wildlife watchers report a Red-Banded Leafhopper in Detroit on a given day, against under 5% in November to May, the lowest months.
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.
Yes
Of the 17 cities where we can rate Red-Banded Leafhopper sightings, Detroit has the highest daily chance: about 20%. Next come Boston (United States, about 20%) and Minneapolis [Saint Paul] (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Red-Banded Leafhopper is recorded against all the insects logged in Detroit (78 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.
