Phloeosinus aubei

Small cypress bark beetle

Description

2.0–2.5 mm. Bivoltine. The vertical egg gallery is 4–8 cm long, occasionally forking. The irregularly curving larval tunnels are excavated into the sapwood. The adults feed in one-year-old shoots. The shoot above the attack fades, becomes dry and red, and later falls from the tree. Can cause severe damage (including tree death), particularly when trees are weakened by several consecutive years of drought. Parks, gardens. The related species Phloeosinus thujae is found in southern parts of Europe commonly on juniper and cedar trees.
