Surveying for the Bog Pseudoscorpion Microbisium brevifemoratum on the raised bog at Cors Fochno (Dyfi SSSI)
This project surveyed Cors Fochno in October/November 2022, using standardised vacuum sampling, for the very rare Bog Pseudoscorpion Microbisium brevifemoratum(Ellingsen, 1903). A total of sixty-two minutes of vacuum sampling was undertaken during the survey at 17 sample points. In total, five specimens of M. brevifemoratum were found at two sample points during the survey. A single adult at SN63849084 (29th October 2022) represents a new location, with a further four adults found at SN64029087 (22nd November 2022) very near to where the species was found in 2021.

Timed vacuum sampling using a petrol vacuum sampler (Stihl SH56C), as described in Gallon (2022), was the main survey method employed. A total of 62 minutes of vacuum sampling was undertaken during the survey at 17 sample points (Figure 1, Figures 6 to 22). The resulting sieved vacuum samples were examined with x2 magnification glasses to find Microbisium specimens and spiders (Figure 2). A clump of Sphagnum was sieved over a tray in the field at SN63809102 (Figures 3 & 13).Two samples of Sphagnum from SN63989088 (Sample Point 3) and SN64029087(Sample Point 13) were subjected to Tullgren Funnel extraction in the lab (Figures 4 & 5). Here, Sphagnum moss was placed on a wire mesh grid within a large plastic funnel and subjected to a 25W incandescent light bulb from above. This method slowly dries out the moss and any hidden invertebrates are driven downwards, falling through the funnel and into a sample pot of preserving alcohol. As Tullgren Funnels are widely used for surveying pseudoscorpions from leaflitter, straw and moss, it was felt this would be worth trying during this survey.
