Urocerus fantoma (Fabricius, 1781)

Urocerus fantoma

Not established in Britain or Ireland. A rare introduction in imported timber.

The female has an orange brown abdomen with a black band across tergites 6 and 7. Very similar to Urocerus augur and can only be separated by having a very small inner tooth on the tarsal claw, which is larger in U. augur.

Urocerus fantoma larvae feed in timber of coniferous trees and take 2 to 3 years to develop.
