Was working through verifying some records and came back to this one. https://irecord.org.uk/record-details?occurrence_id=27648389. A few days ago when I commented the vernacular name as correctly Common Wainscot (that is the one the scientific name Mythimna pallens relates to). When I looked at it again today it was listing the vernacular name Matthew's Wainscot.
Thanks David, we'll get that corrected.
