DAY OUT IN NORTH WALES

Jenna, Harley, and I visited the Pensychnant Nature Reserve in North Wales this morning. It was an open day for the public to learn about the reserve's daily operations.

We had a few informative hours, during which I saw some moths I needed for my list, as they had been trapped overnight. While I enjoyed a drink and homemade cake, a Hummingbird-hawk moth put on a fantastic display on the nearby buddleia.






After the event, we met up with my good friend Marc Hughes and spent the afternoon on the Great Orme near Llandudno.


During our walk, Jenna was thrilled to add the Silver-studded Blue butterfly to her list.


The subspecies Plebejus argus caernensis emerges about a month earlier than others in the UK. Its life cycle is unique, as black ants care for the caterpillars, taking them into their nests and protecting them. When the caterpillars feed, the ants accompany them and, in return, consume a sugary solution that the caterpillars produce.

Another new sighting was the Grayling butterfly, a distinct subspecies, Hipparchia semele thyone, recognised for its smaller size and earlier emergence compared to other UK populations.


The butterfly is common in Europe but is decreasing in both distribution and numbers in the UK. It is considered to be at high risk across Europe due to anticipated climate change.

We also encountered the Horehound Plume moth and its larva next. This micro-moth has been the focus of a project called "Cryptic Creatures of the Creuddyn," which surveys its limestone habitats on the Great Orme and surrounding areas.

Walking over the Great Orme, we came across other species of moth: 

Silky Wave

The species name ‘dilutaria’ is derived from the Latin word "dilutus," which means "washed-out." This refers to the pale colour and faint wing markings of this small and delicate moth. In recent years, the species has been recorded at only a few locations in Wales and western England, including the Great Orme in Conwy, the South Gower coast in Glamorgan, and the Avon Gorge near Bristol.

As the afternoon was coming to the end of are walkover, we found 4 Slow worms basking in the sun


A great day and loads of first records for us all.

Marc, Harley, and I.
