Chrysomela populi, commonly known as the poplar leaf beetle, is a species of broad-shouldered leaf beetle belonging to the family Chrysomelidae, subfamily Chrysomelinae. There are more than 25 thousand species of Chrysomelidae in the world. Many of its species carry the reputation of being agricultural and forest pests and Chrysomela populi is one of the most important and populous species of this group. C. populi is a broad-shouldered leaf beetle belonging to the family Chrysomelidae and subfamily Chrysomelinae. The species inhabits plant species of the family Salicacae and its activity favors moderate winters and dry, warm springs. Increased food quality and favorable living conditions has led to an increase in the population density of Chrysomelidae, including C. populi. C. populi have been commonly spotted in Eastern Europe and can be found throughout Asia. Specifically, they can be found living on species of Salix, like S. triandra, S. fragilis and S. viminali, and Populus, such as P. tremula, P. alba, and P. nigra.
C. populi selects hosts based on nutrient content and proportion, and it generally has high requirements for food quality. C. populi leaves behind... Wikipedia →

Rare
Under 5% of wildlife watchers report a Poplar Leaf Beetle sighting in Pyrénées National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 738th most-seen of the 1277 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–June and December
In those months about 10% of wildlife watchers report a Poplar Leaf Beetle in Pyrénées National Park on a given day, against under 5% in January–March and July–November, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Poplar Leaf Beetle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
8th of 8
Of the 8 parks where we can rate Poplar Leaf Beetle sightings, Pyrénées National Park ranks 8th at under 5%. The best odds are in Biebrza National Park (Poland, about 20%), Białowieża National Park (Poland, about 10%) and Bavarian Forest National Park (Germany, about 10%).
GBIF citizen-science records
It is estimated from how often the Poplar Leaf Beetle is recorded against all the insects logged in Pyrénées National Park (10 verified sightings from 2019 to 2026), 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.
