Xanthogaleruca Luteola: Elm, Larva, Imago, Dutch Elm Disease, Elytron, Chaetae - Tapa blanda

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Xanthogaleruca luteola, commonly known as the Elm Leaf Beetle, is a serious pest of the elm. Indigenous to Europe, it was accidentally introduced to North America. Both the imagines and larvae feed on the emergent leaves of the elm. Repeated heavy infestation rarely kills the tree outright, rather it usually weakens it, rendering it vulnerable to attack by other insects and diseases. However, the beetle does not transmit Dutch elm disease. The imago is 6–8 mm in length, ranges from yellow to green in colour, with a spot on its head, an hourglass mark and two spots on the pronotum, and a broad, dark stripe along the edge of each elytron.
