Garden Tiger Moth Arctia caja
Young larvae that in the wild would hibernate and if kept warm and active, could develop and produce another generation this year. If young larvae are released into hedgerows, there is the opportunity to introduce Woolly Bears back into the countryside, where once they were abundant each spring.
Garden Tiger larvae Woolly Bears grow fast on Dock, Dandelion, Dead Nettle, Nettle and many other hedgerow plants, also Pussy Willow Salix caprea and Osier Willow Salix viminalis. You can also feed them conveniently on Cabbage.
Now a most difficult species to obtain.
In the wild, late summer larvae would hibernate, but if you keep them warm and light, many will produce another generation this year.
If you wish to hibernate Wooly Bears, sleeve them in autumn on Willow or Sallow (Pussy Willow). The falling leaves curl to form a ventilated ball in which the larvae hibernate. If all goes well in winter the larvae emerge in spring and feed from the new spring leaves.
