We watched this sample area for 20 minutes just after noon in full sun. During that period there were three insect interactions, one very brief. One of the 63 plants was visited twice, surprisingly as it was only just breaking into flower. The insects involved were all Rhingia campestris, not a known pollinator (The Flower of the European Orchid; Claessens and Kleynen), and indeed checking the plants involved, none of the pollinia had been removed.
The previous day I joined a recording group at Foxholes Wood, another BBOWT reserve, this time near Kingham. As ever I found my patience and ID skills were well short of what was required, so I wandered off to see if I could find Herb Paris for which there are a few records. I was not successful, and on rejoining the group they pointed me in the direction of some Early purple orchids which I had missed, growing in a damp shaded area by a stream, a complete contrast to the habitat at Westwell - grazed turf.
