In 3 days ~10% in a week ~30%
Potato leafhopper (Empoasca fabae) belongs to family Cicadellidae and genus Empoasca within order Hemiptera. In North America they are a serious agricultural pest. Every year millions of dollars are lost from reduced crop yields and on pest management. Crops that are impacted the most are potatoes, clover, beans, apples and alfalfa.
Adults have pale to iridescent green bodies with 6 or 8 white spots on their pronotum. They have a distinctive white H shape mark between their head and wing base. Their bodies are approximately 3 mm long and have on their front wings near its tip a crossvein. Adults and nymphs move by hopping among host plants. However, only adults can fly.
They are able to feed and reproduce on at least 200 different plant species across twenty-six families. In total herb genera represent 64% of their hosts. Adults prefer to feed on the leaves and stems, while the nymphs prefer the leaves. Their specialized mouth parts are able to pierce into the plant tissue and remove its sap. The ability to inhabit a wide range of hosts is due to the variation in their feeding behaviors.
Empoasca fabae is a seasonal migration species. If... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Potato Leafhopper is recorded against all the insects logged in Dallas (48 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.
