Birch Sawfly Cimbex femoratus pair Freshfield Dune Heath 13 7 21

Extreme heatwaves and prolonged spring and summer droughts are a predicted consequence of climate change. Fortunately, most of our sand-dune specialist flora and fauna seem able to cope at present, being adapted to life in harsh conditions.

 A loud hum preceded the arrival of two enormous, tropical-looking insects that crashed into the grass a few yards away; each was over an inch long and their identity had me foxed until my photographs confirmed a mating pair of the Birch Sawfly. I've never seen one before and I was able to trace only a single previous Sefton record of a really impressive creature.
