A couple of weeks ago a young boy brought in the yellow caterpillar (or so we thought) into the visitor centre. After a failed search in the internet, a photo was put onto Ispot and I contacted the Norfolk Moth group for advice. An answer came back quickly that it was probably a sawfly larva. After more looking it turn out to be a very rare and under-recorded species called Cimbex luteus and is only the 3rd modern record and 1st for Norfolk. Much interest has been caused and an expert visited the reserve today. Unfortunatly he didn't find any further signs but amazingly he did find another sawfly. This time is was the commoner Cimbex connatus or alder sawfly in the trees by the picnic area.
It just shows what is out there if you look hard enough!
Work is going well with the reserve upgrades and hopefully the path will be open to Island Hide in the next few weeks. Thankfully, nothing too good has been seen but upto 300 dunlin, 9 curlew sands and 3 little stint has been nice.
