Dr Phil Smith: Wildlife notes August 2021

Goldenrod Solidago virgaurea Falklands Way 22 8 2021.jpg

My month with nature started well when Joyce and David Jarvis showed me two flowering Broad-leaved Helleborines at Ainsdale National Nature Reserve. I hadn’t seen this orchid on the Sefton Coast since 2008.  Other notable plants during the month included a small colony of Whorl-grass that I found on a freshwater seepage zone on Hightown beach. It turned out to be the rare variety uniflora, largely confined to Western Scotland with only two known localities in England. While listing the associated species, I came across a plant that I couldn’t name but which seems to be Touch-me-not Balsam (Impatiens noli-tangere), not previously recorded for the Sefton Coast.

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.

Narcissus Bulbfly Merodon equestris pair Hawksworth Drive

May 2021 was one of the wettest on record. Some parts of the country had more than twice their normal rainfall. Most insects like it warm, so May’s cool conditions should have meant fewer of them. This was not at all the case. Spring species are well-adapted to the cold and if it’s cool they spend more time basking in the sun to warm up, making them easier to find.

Dr Phil Smith: Wildlife notes March 2021

​  Large Bear-hoverfly (Criorhina ranunculi) Ainsdale NNR  ​

March was a relatively dry, settled month with measurable rain on only 10 days. However, wetter conditions from 9th to 16th raised the water-table at the Devil’s Hole to the highest level since I started measuring it in October 2015. The usual spring high pressure became established towards the end of the month, the warmest ever March temperature of 24.5 degrees being recorded in London on 30th. In Formby, it peaked at more reasonable 20 degrees. These spring heat-waves are becoming more frequent, as a predicted consequence of climate change.

Snow Bunting Ainsdale Beach, Pete Kinsella

It was a wet one; measurable rain fell in Formby on 20 days during December. The 13th, 19th and 26th were especially damp, the latter coinciding with named storm ‘Bella’. It was also relatively mild, with frost largely restricted to a few mornings late in the month. There was no snow; indeed, it is now ten years since the last major snowfall here in December 2010. Unsurprisingly, the sand-dune water-table at my measuring point in the Devil’s Hole blowout rose by about 9cm (3.5 inches), in marked contrast to the previous month, when there was no change in the level.

Goat Moth (Dr Phil Smith)

On average, August is the wettest summer month, so it wasn’t surprising that we had rain on 14 days. Most of it was light but the second week was warm and humid, culminating in a thunderstorm on the 10th. The spring drought seemed a distant memory as late summer flowers like Grass-of-Parnassus proliferated in the damp conditions. Many of our dune-slacks didn’t dry up at all, my measuring point in the Devil’s Hole at Ravenmeols registering shallow water throughout.

Our concerns about the absence of Six-spot Burnet moths in July proved unduly pessimistic, their numbers rapidly increasing in early August, joining the second generation of Northern Dune Tiger Beetles. The latter seems to have done particularly well this year, Gems in the Dunes staff reporting hundreds in their usual bare sand habitat, mostly on the frontal dunes. A large area of flowering Apple Mint (the “mint patch”) at Ravenmeols attracted a wide range of insects, though the number of butterflies was down on last year. Even so, the glamorous Red Admiral, Peacock, Comma and Small Tortoiseshell, accompanied more mundane Gatekeepers. I was especially pleased to find two Small Heaths, a butterfly that is declining nationally but is still plentiful on the Sefton Coast. Amongst a wealth of bees and flies on the mint, the impressive Tachina fera attracted attention. This is a large bristly fly that parasitises various moth caterpillars. The female lays its eggs on leaves. When the eggs hatch, the young larva enters the body of a caterpillar and eats it from the inside.  This fly is widespread and common throughout much of the country, having a successful life-style shared by a great number of flies and wasps. These include a group of flies known as “beegrabbers” from their habit of jumping on bees and laying an egg on them. The larva develops inside the bee and eventually kills it. I found the widely distributed Four-banded Beegrabber on several occasions but the much rarer Dark-cheeked Beegrabber was a particular highlight, two being photographed on Ragwort at Ravenmeols on 18th. Two Common Lizards basking on a nearby log pile was a distraction from the insects.
