Coleopteran insect of around 4-5 mm in its adult instar, bright metallic blue or green (Fig. a).
Damages very similar to those caused by the elm leaf beetle; it feeds on the leaves of poplars and willows, leaving them full of holes and transparent (this is if they only eat the parenchyma). Although they have rarely been seen in our country, in severe cases it can cause strong defoliation.
As this is a rare pest, curative treatments are most often carried out. The optimal time for treatment should be when the first signs are detected.
