Synophropsis lauri
In 3 days ~20% in a week ~40%
Synophropsis lauri, sometimes called the bay leafhopper, is a species of leafhopper of the subfamily Deltocephalinae, tribe Fieberiellini. It is the only species in the monotypic genus Synophropsis. The hemelytra vary from greyish to brick-red (some sources say the males are grey, females red) and are somewhat translucent with the veins showing up as whitish. The wings darken towards the tips. There are small dark marks along the suture and at the distal ends of some of the long veins. The head is yellowish and the vertex is sharply pointed. Antennae are filamentous and very long. Size: up to 6.5mm long, or even 7mm.
Nymphs are green, and over-winter. The species is normally said to be univoltine, but it is possible that the females hibernate and produce a second generation. The species was first described, as Thamnotettix lauri, by Géza Horváth in 1897 from specimens taken in Fiume (Rijeka) and Buccari (Bakar) on the Adriatic coast of what is now Croatia. Nearly 30 years later, Hermann Haupt independently described a single male taken in Gravosa (Gruž), some 260 miles (420 km) further southeast. Haupt placed it in a new genus as Synophropsis...

With luck
About 10% of wildlife watchers report a Bay Leafhopper sighting in Berlin on a given day, based on 72 verified sightings from GBIF citizen-science data. It is the 182nd most-seen of the 1065 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
July to February
In those months about 10% of wildlife watchers report a Bay Leafhopper in Berlin on a given day, against under 5% in March to June, the lowest months.
Among the best
Of the 9 cities where we can rate Bay Leafhopper sightings, Berlin ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Madrid (Spain, about 10%).
Same family: Cicadellidae
The closest relatives of the Bay Leafhopper that you can see in Berlin (family Cicadellidae, Typical Leafhoppers) are Zyginella pulchra (about 10%), Rhododendron Leafhopper (about 10%) and Japanese Leafhopper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Bay Leafhopper is recorded against all the insects logged in Berlin (72 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.
