Marsh fritillaries and dormice in Ceredigion

We continued and finished our marsh fritillary larval web surveys on our rhos pasture sites- walking a transect through the grassland looking for the webs that hold the small black caterpillars of the marsh fritillary butterfly, on the leaves of the devil’s bit scabious, their food plant.

We had another good day at Rhos Glyn yr Helyg where we found another 11 webs in the other half of the site, taking the total to 42 live webs found with several old ones. A four-fold increase on last year! Not such a good result at Rhos Fullbrook where we only found two webs but at least they are still there! Once again we didn’t find any caterpillars at Rhos Pil Bach.

A very successful day checking the dormouse boxes and tubes at Cwm Clettwr found 5 dormice and 7 wood mice (all male) plus several other nests in both the boxes and tubes (for the first time) and in bird boxes.

We moved away from summer tasks to more autumnal ones with the cutting of the Coed Maidie meadow and spent a beautiful sunny day at Cors Ian clearing another patch of the burnt, dead gorse on the hillside. We’ll be clearing scrub and starting woodland thinning from now on.
