The Status of the Snowdon Beetle Chrysolina cerealis on Yr Wyddfa (2016)

  • All

The Snowdon Beetle Chrysolina cerealis is restricted in the United Kingdom to Snowdon (Yr Wyddfa), although it was also found in Cwm Idwal until 1980. As recent records of the beetle have been few, a survey was undertaken in 2015 (NRW_DS116513) in an attempt to determine its status and distribution. A total of five beetles (four larvae and one adult) was found following 63.5 hours of hand searching on and around thyme plants (the only recorded foodplant of the beetle in the UK) and stone-turning near patches of thyme from June to September 2015, with all specimens found in Clogwyn Coch in September. No beetles were found in Cwm du'r Arddu, its traditional hotspot, despite exhaustive searches. A continuation of the survey from May to October 2016 located ten adults and one larva following 69 hours of search, with all adults recorded in Clogwyn Coch and the larva found under a stone in Cwm Glas Bach. The 2016 survey reinforces the suggestion that the beetle may be retreating to higher altitudes, perhaps as a consequence of climate change or other factors. Over the two year period, 16 beetles (11 adults and 5 larvae) have been found after more than 130 hours of search. As in 2015, no beetles were found in Cwm Idwal.
