 part of May, but chiefly in June. The female lays her eggs 

 where a small twig breaks off, and also on the buds, the larvas 

 making their way into the centre of the shoots. The caterpillars, 

 which are creamy-white, tunnel both up and down the stems dur-

 pushes its way out of a hole (fig. 80, a) previously formed by

 during the early hours of the morning, when they may be seen 

 hovering over the currant-bushes.
