Ptosima undecimmaculata

Jewel beetle Ptosima undecimmaculata

Description

Ptosima undecimmaculata, is a polyphagous buprestid beetle whose larvae develop under the bark of weakened or injured branches and trunks of deciduous trees. It prefers warmer climates and attacks especially fruit trees such as plum, apricot, peach, and cherry. In some areas, especially vineyards, it has been reported as a significant pest. Larvae feed on the cambium and sapwood, creating irregular feeding galleries and disrupting the tree’s nutrient flow. Adults emerge between March and July and feed on bark and leaves. The species has a life cycle lasting over one year and can cause dieback and tree mortality under favorable conditions. In Europe, it is found mainly in southern and southeastern regions.

Exit holes in the bark, irregular larval galleries under the bark, withering of shoots, and premature yellowing and drying of leaves and branches.
