Black-veined White crataegi Egg Batch

Black-veined White Aporia crataegi 

 Egg batches (at least 30 eggs) can be attached to growing shoots in a sleeve. Let the larvae create their protective tent and allow them to hibernate there without disturbance, to re-appear in mid-March.

The larvae do well sleeved on Hawthorn (their preferred foodplant), Plum, Blackthorn, Plum or Apple. They live gregariously, spinning a very small and concealed web on the branch, in which they hibernate. The webs appear to be dead leaves, but the larvae spin a very strong silken life-line which is an indication of life inside the apparently dead leaf! Leave the sleeve untouched for the winter.  

In spring they awake as soon as the buds burst, and begin to grow very quickly. They pupate often collectively, making very brightly coloured, angular pupae which are greenish white, with contrasting markings in black and yellow.
