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 →
