Description


A diary of my mothing activity covering highlights and photos from my moth trapping activities. Mainly Norfolk (UK), occasionally beyond. I may mention other wildlife sightings here, especially insects, but for birds see my birding diary.

Review of 2019 and 2020 - Moths: Case-bearers (Coleophoridae) (Part 4)

CASE-BEARERS (COLEOPHORIDAE) continued


Buff Rush Case-bearer Coleophora caespititiella - Totals of 128 trapped at home between 25th May and 29th June 2019 and 79 between 20th May and 22nd June 2020, although on the busiest days some of these were not gen detted.  Peaks of 28 on 3rd and 7th June 2019 and 14 on 26th May and 12th June 2020.  2019 was my best year for this species although I had a higher count of 51 in 2018.  This is my commonest Coleophora here.  Also 12 confirmed from the Cathedral Meadows and singles at Bintree Wood, Frost's Common and Hills and Holes.  Typically this species is distinctly plainer (other than the pale costa) than alticolella and glaucicolella however there is variation.  Very occasionally a plain individual turns out to be one of the other species and caespititiella can have faint pale streaking inside the costa, albeit rarely as clear as it usually is on the other 2 species.

Jointed-rush Case-bearer Coleophora tamesis - None.  I've never seen this species but although it's described as rare there are records from a little further up the valley so it's a possibility here.


Grey Rush Case-bearer Coleophora glaucicolella - 2 at the meadows on 25th May followed by 1 here on 1st June and another 10 here between 6th and 23rd July.  Also 2 at Weybourne.  11 here is a good tally - numbers fluctuate quite a lot with 17 in 2016 but only singles in 2017 and 2018.  A similar pattern in 2020 with the first at the meadows (on 17th May) well before those at home (5 between 26th June and 23rd July).

Wood-rush Case-bearer Coleophora otidipennella - None.  I've only ever had one here, in 2017.


Common Rush Case-bearer Coleophora alticolella - 8 trapped here between 25th May and 23rd June 2019 and 14 between 21st May and 15th June 2020, my best years for this species here (previous annual totals varying from 1-5).  Also recorded at the meadows on 6 dates.

Small Rush Case-bearer Coleophora taeniipennella - One caught in the garden on 23rd July 2019, my third following singles here in 2016 and 2017.  None in 2020.

Black Bindweed Case-bearer Coleophora therinella - One trapped at Weybourne on 5th July 2019, the 9th record for Norfolk.  Despite the paucity of records I've had this species here in 2016 and twice at my last house in Bawdeswell (when I was only retaining a minority of Coleophora for confirmation).

Orache Case-bearer Coleophora saxicolella - A new moth for the garden when one was trapped on 4th August 2019, followed by a second on 9th August and a third on 9th August 2020.  Also one at Weybourne on 5th July 2019.  Although this species requires gen detting to separate from the next species, the small size and pale costa was a strong clue on a couple of these.

Speckled Case-bearer Coleophora sternipennella - Just the one in 2019, here on 16th July, and none in 2020.  Only one in 2018 too but I have had as many as 12 in a year (2016).

Pale Orache Case-bearer Coleophora versurella - Singles in the garden trap on 25th July 2019 and 7th August 2020, and one at the meadows on 18th July 2020.  I had only ever recorded one before, and never here in North Elmham.
