Surveys for additional populations of Scaly Cricket Pseudomogoplistes vicentae in Pembrokeshire and west Carmarthenshire in 2023 and 2024
The current two-year survey visited a further eleven sites in Pembrokeshire and one in west Carmarthenshire. A single Scaly Cricket nymph was found in a pitfall trap at Monkstone Beach near Tenby in October 2023. An additional seven nymphs were recorded at the same site in October 2024, again in pitfall traps, suggesting that a resident population is present. This represents the 4th known locality in Wales, all of which are in Pembrokeshire, and the 6th in the UK.
The current survey suggests that there are few suitable beaches for Scaly Cricket and that, even where suitable habitat is present, it is not always utilised by the species which seems to have a very restricted distribution. The survey further highlights the importance of the Marloes Sands population as it is clearly the largest in Wales. Populations at Marloes Sands, West Dale Bay and Monkstone Beach remain very vulnerable to habitat loss due to coastal erosion and sea-level rise.

Hand Searching
Within areas of suitable habitat, large pebbles, cobbles and stones were swiftly removed or lifted by one edge. Large pebbles beneath the lifted stone were then removed to a depth of around 10-20cm. Where the upper layers of the beach deposits have become dry these were removed and the above search methods were applied to the newly exposed, damper layers. Searches were focussed on areas of suitable habitat where strandline deposits were present.
Pitfall Trapping
A plastic pint beer glass was sunk into the beach deposits. The bait used was dried cat biscuits and pieces of cooked sausage. Fine shingle was placed around the traps to ensure invertebrates were able to access the traps and a large flat stone was placed on top of the trap. Trap locations were marked by pebble cairns and photographed to aid relocation.
