Copper-tipped Ermine Pseudoswammerdamia combinella - Singles in my garden moth trap on 1st June 2019 and 27th May 2020 were only my second and third records ever (first was here in May 2015).

Birch Ermine Swammerdamia caesiella - One in the garden trap on 30th July 2020. I've only recorded this species twice before at home, in 2016 and 2018 - surprisingly scarce for a common birch-feeding species (there is a birch in my front garden and huge one in next door's garden). Although this is grade 2 it would take a very clear and fresh example to satisfy me the ID was correct without gen detting.

Little Ermine Swammerdamia pyrella - One at the meadows on 25th May 2019 and then 11 in my garden between 21st July and 8th August, the worst showing here four 4 years. A more typical 25 in my garden between 16th July and 13th August 2020. Although fresh examples can be straightforward I find I have to confirm a lot of these by gen detting. Some of the other species in this group can show a slight purply or coppery sheen to their terminal cilia (including Paraswammerdamia nebulella for example) and worn pyrella can lose this altogether. Other characters don't seem to be very reliable either, at least on any but the freshest specimens.

White-headed Ermine Paraswammerdamia albicapitella - 4 trapped at home and one at the meadows between 5th June and 30th August 2019 making it my equal-best year for this species, but this was bettered in 2020 when I caught 6 in the garden and 3 at the meadows between 25th May and 19th August. Beware worn nebulella which can look very white on the thorax - I gen det any that aren't fresh and obvious and sometimes get a surprise.

Hawthorn Ermine Paraswammerdamia nebulella - 10 trapped here between 23rd June and 25th July 2019 and 11 between 18th June and 31st July 2020. Both fairly average years though well down on the 21 in 2018.

Brown Pine Ermine Cedestis subfasciella - One at Bintree Wood on 13th June 2020 and singles in the garden on 5th and 15th August. I'd only ever seen one before, in my garden in 2015.
