Our latest butterfly news – September 2017: Clouded Yellow on Poet's Walk summer 2017

The year has continued very well with higher numbers reported than last year in spite of the recent poor weather.

Recorders have managed to find a decent weather window for every week and a total of 21 species have been seen so far.

The highlight of the year so far is Sue’s sighting of a Clouded Yellow, confirmed by her own photograph (right).

The Friends of Poets’ Walk are taking part in The UK Butterfly Monitoring Scheme using a fixed-route walk (transect) over Church Hill and Wain’s Hill drawn up and registered on-line last year (2016) by our butterfly representative Bill Thompson.

Our sightings in 2016 are summarised in Bill’s end of season summary

Church Hill and Wain's Hill Butterflies Transect 2016

To take part in the scheme a transect must be established at a chosen site and butterflies are recorded along the route on a regular (weekly) basis under reasonable weather conditions for a number of years. A transect route is divided into sections, which are chosen to represent the various habitat types and management activities across the site. It must remain unchanged to enable butterfly sightings to be compared from year to year.

Butterflies are recorded from the beginning of April until the end of September. Certain requirements apply relating to time of day and weather conditions. Data is recorded and summarized results submitted to the UK Butterfly Monitoring Scheme (UKBMS).

Our Church Hill and Wain’s Hill transect is divided into nine sections starting at the path (Hack’s Way) on Old Church Road and ending on the coastal path. Its total length is about 2.6 km (1.6 miles) and the walk takes around one hour.
