Macrosteles quadrilineatus, the aster leafhopper or six-spotted leafhopper, is a leafhopper species in the genus Macrosteles, found in the United States. It is the vector of aster yellows disease, which affects various vegetable plants, weeds and ornamental plants.
The aster leafhopper is a small species, with males reaching about 3.3 mm (0.13 in) in length and females about 3.7 mm (0.15 in). The fore-wings are greyish-green while the abdomen is yellowish-green. Six pairs of minute black spots or streaks on the head give the insect its alternative name of six-spotted leafhopper.
In the United States, strong southerly winds in the spring carry adults northwards to the Mid West and northern parts of the country, and these insects usually arrive earlier and exceed in number the resident insects that have been overwintering there, mostly on grasses and cereals. Eggs are laid on a wide range of host plants which include grasses and clovers, corn, oats, rye, carrots and various weeds. The eggs hatch in about one week and the whole life cycle takes about four weeks. Carrot, dill, potato and radish are selected by adults for feeding purposes but are not good... Wikipedia →

Rare
Under 5% of wildlife watchers report an Aster Leafhopper sighting in Dallas on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 1136th most-seen of the 1412 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Aster Leafhopper in Dallas on a given day, so our monthly data shows no clear season.
Only Dallas, in our data
Dallas is the only city on Wallace's Line with enough records to rate Aster Leafhopper sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Cicadellidae

GBIF citizen-science records
It is estimated from how often the Aster Leafhopper is recorded against all the insects logged in Dallas (7 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.
