Leaders: Paul Waring & Mick Beeson.
Meet at 8pm at grid ref. TF 11600 03167 just inside the site entrance on the road from Marholm, just past Willowbrook Farm Shop and the two cottages on the opposite site of the road.
The main aim of this meeting is to operate light-traps from dusk to dawn to sample the nocturnal moths. We particularly hope to record the Concolorous Photedes extrema for which there are occasional previous records from the garden of Scotsman’s Cottage adjacent to this site. Within a couple of days of the chosen date for this meeting, in 2014, the leader (PW) found the Concolorous flying in good numbers at Orton Pit which is only a few kilometres away on the south side of Peterborough.
Swaddywell Pit has the potential to support many species which are nationally or locally scarce. It is a very interesting site with a range of early successional stages of habitats, all on calcareous substrates. Habitats include reedbeds and other pool-side vegetation, willow carr, mixed scrub and hedgerows and open limestone grassland rich in orchids.
This field meeting has been deliberately organised to follow on from the meeting at nearby Castor Hanglands the previous night so that it will be possible for BENHS members to have off-road parking at both sites and to explore both for wildlife by day as well as during the night sessions.
In addition to members bringing overnight gear and food, hot meals are served from breakfast to dinner-time at the nearby Fitzwilliam Arms in Marholm.
