Gooseberry Knot-horn (Zophodia grossulariella). Moth that deposits its eggs on flowers or incipient berries. The larvae (caterpillar) crawls into a berry and spins threads around the berries nearby. Often the caterpillar is limited to a single berry. The affected berry discolors and ripens prematurely. The damage caused by the caterpillars remains limited.
The Gooseberry Knot-horn is known throughout Europe but in Britain is a rare visitor.

Where to find

  • Gooseberry

Control

Remove a single affected berry. It can be recognized by its premature ripening with the accompanying discoloration.

Prevention

The damage caused by the Gooseberry Knot-horn is low – prevention is not really necessary.
