Bird-cherry Ermine Yponomeuta evonymella - Recorded at home on 30 nights between 9th July and 22nd August 2019. This included some nights where no count was made but over 130 individuals involved in total with a maximum count of 27 on 10th July. A record-breaking 509 recorded at home in 2020 on 40 nights between 26th June and 21st August including peak counts of 84 on 18th July and 80 on 24th July. Also recorded next door, at the meadows a couple of times both years (up to 15), at Bintree Wood and at Brancaster. Lots of larvae noted at Hills and Holes on 21st May 2020.

Ochard/Apple/Spindle Ermine Yponomeuta padella/malinus/cagnagella - These 3 species cannot be separated as adults (even with reference to their genitalia) at least in the majority of cases and when there is no clear association with their larval foodplant. A total of 13 aggs. at home between 20th July and 28th August 2019 and 19 between 26th June and 24th August 2020. Although none of these were, a couple in 2018 were distinctly grey which I understand is at least indicative of Orchard Ermine Yponomeuta padella - but I'm not sure how reliable that is? Elsewhere singles at the meadows both years and one at Whitwell Street on 3rd September 2020.

Brown Ash Ermine Zelleria hepariella - None. I've only ever seen 2 of these, one here in 2015 and one at my old house in Bawdeswell in 2011. There were more county records in 2019-20 than there had ever been up to 2018 so another one can be expected before long.
