Rare
Under 5% of wildlife watchers report a Rice Root Aphid sighting in Bucharest on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 303rd most-seen of the 361 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April–May and August
In those months about 10% of wildlife watchers report a Rice Root Aphid in Bucharest on a given day, against under 5% in June–July and September–March, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Rice Root Aphid sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
6th of 19
Of the 19 cities where we can rate Rice Root Aphid sightings, Bucharest ranks 6th at under 5%. The best odds are in Budapest (Hungary, about 10%), Turin (Italy, about 10%) and Detroit (United States, about 10%).
Same order: Hemiptera
The closest relatives of the Rice Root Aphid that you can see in Bucharest (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are European Firebug (about 30%), Southern Green Stink Bug (about 20%) and Mediterranean Spiny Stink Bug (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Rice Root Aphid is recorded against all the insects logged in Bucharest (5 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.
