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 Yekaterinburg on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 74th most-seen of the 155 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.
May and June
In those months about 10% of wildlife watchers report a Poplar Leaf Beetle in Yekaterinburg on a given day, against under 5% in July to April, the lowest months. Those are among Yekaterinburg's wettest months, with about 80 mm of rain a month against 25 mm in February.

GBIF citizen-science records
It is estimated from how often the Poplar Leaf Beetle is recorded against all the insects logged in Yekaterinburg (12 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.
