I had a late common blue butterfly on the wing this morning on the visitor trails at the eastern end of the boardwalk. The butterfly was feeding on the last remaining ragwort flowers - a good source of late nectar there. Clouded yellow was still flying last weekend, with one seen by volunteer John Ellis and red admiral, small tortoiseshell and comma are all still active.
Migrant hawkers were plentiful last week and common darters are still around in good numbers, even on cooler days they seem to be rather active.
We may have some late dates for insects this year if the warm weather continues....
