Adult Brimstones are typically on the wing from April to October. In southern regions, there are often two or even three overlapping generations, while in our cooler northern parts this may reduce to a single brood. The species is strongly attracted to light and can often be found resting on walls or fences near outdoor lamps.

Common Bistort
The pink flower spikes of Common Bistort, towering over other wildflowers on their tall, straight stems, are a familiar sight to many of us who have walked the highways and byways of Northwest England in spring and early summer.
Mute Swans: Graceful Guardians of the Water
Mute swans (Cygnus olor), with their snowy white plumage, elegant S-curved neck, and bright orange bill topped with a black knob, are one of Britain’s most iconic waterbirds and particularly fond of our 2,700-odd miles of canals.
Here in the Northwest we are lucky enough to have over 438 miles of these waterways, namely the Lancaster, Leeds & Liverpool, Bridgewater, Macclesfield, and Manchester Ship canals, upon which these majestic birds are a common and welcome sight, even in the heart of our largest and busiest cities.
Speckled Woods
Speckled Woods are a familiar butterfly to most of us here in Britain yet are often overlooked in favour of flashier species like the Peacock or Red Admiral.
Understated and widespread they may even appear dowdy compared to their lepidopteran cousins yet, as with any wild creature, patient observation reveals them to possess more beauty and character than you would ever suspect.
Purple Saxifrage, Jewel of the High Fells
A creeping, mat-forming plant Purple Saxifrage possesses small, opposite, overlapping leaves (hence the latin epithet oppositifolia) that are fleshy with a tiny pore at the tip which can exude lime in calcareous conditions. Its solitary flowers, typically 1 to 2cm across, sit on short stalks and feature five petals ranging from a pale pinkish-purple to rich violet, sometimes with darker veining.
The Duties of a Gamekeeper; Spring on the Moors
For the Upland Gamekeeper spring is a season of intense activity, a critical time of fast change at the fulcrum between the wild & windy months of winter and the more benign months of summer, when the moors become vibrant with life.
Northern Shores: The Common Tern
Adults are very smart and distinguished in their breeding plumage, sporting a silvery-grey back and upperwings, a clean white underbody, and a distinctive black cap. Their bill is long and orangey-red with a black tip, while their legs are short and red. In flight, they show a buoyant, floating style with narrow, angular wings, often hovering before plunging to catch prey.
Northern Shores: Thrift
Thrift is a member of the Plumbaginaceae (aka Leadwort) tribe, a small and tough family that specialises in harsh habitats, having evolved ‘chalk glands’ that excrete salts, allowing it to flourish in places where weaker plants fear to venture, like our storm-lashed, salt-sprayed coastlines.
