On 22nd May this year Woburn Safari Park staff found an unknown larva during their bioblitz, which the Beds Invertebrate Group was also taking part in. I was handed it on the 23rd to identify and found it was a Waved Black larva. I didn't hold up much hope of managing to breed it through but it took bracket fungus from a birch tree and happily munched on this for a few weeks. However, in mid-June before we were due on holiday it was looking a bit lifeless and nearly got thrown out. We kept it and within a couple of days it pupated successfully. Andy checked it on his arrival home from work this evening and found an adult had emerged.
