May Site Focus - Clanger, Picket and Round Woods 

Clanger Wood, Woodland Trust

Lying between Trowbridge and Westbury this collection of three  flower rich ancient woodlands support an amazing range of butterfly and moth species. These are floristically-rich ancient woodlands, and their value to butterflies in particular is nationally recognised and reinforced through their designation as a Site of Special Scientific Interest (SSSI).

These woodlands are also home to a wide range of birds characteristic of ancient woodland in southern and western England. They can be traced back to the time of the Doomsday Book in 1086, and have been managed by the Woodland Trust since 1984.

Visit this month to see an array of spring flowers and butterflies. Download our ID guides for spring woodland flowers and spring woodland butterflies to help you identify what you see. Don't forget to note down your records whilst you're out and then submit them via Living Record.

Species to spot

Pearl Bordered Fritillary, Steve Day/ WWT

One of the rarer butterflies that can be spotted is the Pearl-bordered Fritillary (Boloria euphrosyne). This woodland butterfly gets its name from the series of "pearls" that run along the outside edge of the underside of the hindwing. This beautiful insect is now thought to occur in just half a dozen woods in Wiltshire. Its caterpillar will only feed on violet leaves growing where there is abundant leaf litter, dead bracken or bare ground nearby. These areas absorb the sun's warmth and allow the caterpillars to bask before going off to feed.
