Eucalyptus gall wasp

[jeremiah]

Anybody who happens to be harbouring eucalyptus trees may like to keep an eye out for Eucalyptus galls. A heavy infestation turns the leaves reddish brown and they drop off. This leaf came off the smaller (30ft) of two trees behind a friend's garden. Strangely, the other tree (60ft and growing) doesn't seem to be affected. Maybe the wasps can't fly that high.
