Review of 2019 and 2020 - Moths: Tortrix Moths (Tortricidae) (Part 13: Piercers II (Cydia to Grapholita))

TORTRIX MOTHS (TORTRICIDAE) (continued)


Marbled Piercer Cydia splendana - At least 38 in the garden between 10th July and 2nd September 2019 (though not counted on several dates so possibly more) and 32 between 8th July and 8th September 2020.  Number-wise this species has been fairly consistent here each year.  Elsewhere seen in next door's garden 3 times and at the meadows on 4 dates between 26th July and 3rd September 2019 and 2 on 7th August 2020.  Also at Bintree Wood, Swanton Great Wood and Row Heath (West Runton).

Large Beech Piercer Cydia fagiglandana - Singles at home on 21st and 24th July 2019 but none here in 2020.  2020 wasn't my first blank year but I had 1-2 every year from 2016-19.  Also singles at the meadows on 7th and 26th July 2019 and 3 there on 7th August 2020 plus one at Bintree Wood on 13th June 2020.

Vagrant Piercer Cydia amplana - None.  This species has always been regarded as a rare migrant and as such the odds of me getting one here would be very small.  But in very recent years there have been so many records at inland Norfolk sites it must surely have become established.  Some of these aren't all that far away, like one at Sparham and a ludicrous 20+ that Dave Norgate has had at Toftwood, so I now have high hopes of finding my first before too long.


Scarce Maple Piercer Cydia inquinatana - Having been at the event where Norfolk's first (and Britain's 4th) record of this species was taken, but having not seen it as I didn't hear about it on the night, it was nice to catch one in my own garden on 11th July 2020.  Of course there have been quite a few in Norfolk since that first one in 2011 - I think mine is the 16th.

Red Piercer Lathronympha strigana - 6 between 23rd July and 21st August 2019 and 15 between 21st May and 17th August 2020.  Numbers don't fluctuate all that much here and these were my worst and best years respectively.  Also 2 next door, one at the meadows and one at Bintree Wood.

Triple-stripe Piercer Grapholita compositella - One netted at the meadows on 20th July 2020 was only my second record of this species although it was one I was half-expecting there as there's an abundance of clover.  Not sure how often this species comes to light so my chances of catching one at home are perhaps not so high?

Dark Gorse Piercer Grapholita internana - None.  I've not had this species very locally, though I always look for it around the gorse at the meadows.


Crescent Piercer Grapholita orobana - None.  This seems to be quite a scarce species in Norfolk but there's no reason I can see why it shouldn't occur locally.  I've not seen it yet though, anywhere.


Vetch Piercer Grapholita jungiella - 6 at the meadows over the 2 years between 22nd April and 12th May.  I haven't recorded this species at home yet but I usually see it in the day-time.

Kent Fruit Piercer Grapholita lobarzewskii - following Norfolk's second record in my garden in 2018 I had another 5 in 2019!  The first turned up to the lobarzewskii pheremone lure on 29th June and I imagine the next two were attracted to it to, but they actually turned up in the moth trap that night.  Then there were 2 more to lure on 12th July.  One more in 2020 on 11th July.

Plum Fruit Moth Grapholita funebrana - One at Weybourne on 5th July 2019.  None at home where this species has been very irregular - none most years but 6 in 2016 and one in 2018.  None in 2020.

Deep-brown Piercer Grapholita tenebrosana - None.  I've never seen this species but apparently it comes to the pheremone lure for Grapholita funebrana so I'm hoping to attract one soon.


Pale-bordered Piercer Grapholita janthinana - One here on 27th July 2019 was only my second here to MV light (first in 2015).  2 came to the pheremone lure for Grapholita lobarzewskii on 11th July 2020 (the second time I've caught them here using this method).  Also one to light at Weybourne on 5th July 2019.

First moth-trapping at the meadows

I returned to the Cathedral Meadows early on 4th.  I found six species of moths on the wing: Oak Satin Lift Heliozela sericiella, Common Thorn Midget Phyllonorycter oxyacanthae, 6 Beech Midgets Phyllonorycter maestingella, 4 Horse Chestnut Leaf-miners Cameraria ohridella, Sulphur Tubic Esperia sulphurella and Vetch Piercer Grapholita jungiella.

A variety of other things noted including Muntjac, Large Red Damselfly, Orange-tip, Hemerobius lutescens (a brown lacewing), 3 species of hoverfly (Melanostoma scalares, Syrphus ribesii and one that keys out as Eristalis tenax, looks very much like Eristalis tenax, but lacks any of the 3 characteristics listed in the guide for that species - not sure where I went wrong there or what else it might be!).  Also Small Black Ant Lasius niger, Garden Bumblebee and Common Carder Bees, Kentish Snail and a lifer for me in abundance running through the leaf-litter, Common Fox-spider Alopecosa pulverulenta.

Does anyone know if the species of Oak Gall Wasp can be identified from these galls?

Back at home a beetle dropped onto my outside window sill next to where I was sitting, so I duly potted it up for examination.  It proved to be my first Onthophagus similis.

With cloud forecast from before dusk after a warm sunny day I thought tonight would be a good one to have my first moth trapping session at the meadows.  By the time dusk came the arrival time of the cloud had pushed back to just after dusk, but it was still warm as it got dark and there wasn't much wind, so it promised good.  Sadly the cloud never arrived, at least not before half past midnight, and temperatures soon dropped resulting in a poorer catch than hoped - but not at all bad considering.

The first moth in was this Lunar Marbled Brown - a nice way to begin.

One of the next up was this Knot Grass, a species I never used to encounter before I moved to North Elmham in 2014.  I see them every year now but still good to get so soon.

Also among the first 5 moths to arrive was this Powdered Quaker, my first this year as I don't get many at home (and never seem to get them for a while after others are reporting them).

By now things were really slow, but in the end I did notch up a semi-respectable (given the lack of warmth) 20 species, the others being: Common Oak Purple Dyseriocrania subpurpurella, Parornix sp., Pebble Hook-tip, Frosted Green, Red Twin-spot Carpet, Water Carpet, Small Phoenix, 2 Brindled Pugs, White-pinion Spotted, Iron Prominent, 2 Pebble Prominents, Red Chestnut, 3 Common Quakers, 2 Clouded Drabs, 2 Hebrew Characters, Angle Shades and 3 Nut-tree Tussocks.

There were also 2 Mottled Sedges Glyphotaelius pellucidus (caddisflies) and 2 Black Sexton Beetles.  Nearby there were a couple of White-legged Snake Millipedes and a Common Striped Woodlouse among lots of Common Rough Woodlice.

I didn't catch much at home that night, though Red Twin-spot Carpet was new for the year here.  The rest were Common Plume Emmelina monodactyla, 3 Lesser Swallow Prominents, Swallow Prominent, Muslin Moth and Hebrew Character (also Common Wasp).

Black-headed Gold

On the night of 12th May there were three new moths for the year at home: Brown House Moth Hofmannophila pseudospretella, Common Marble Celypha lacunana and 2 Yellow-faced Bells Notocelia cynosbatella. Not a great deal else: Little Dwarf Elachista canapennella, Many-plumed Moth Alucita hexadactyla, 2 Red Twin-spot Carpets, Common Pug, Scalloped Hazel, 3 Muslin Moths and Hebrew Character.

There was also a Common Earwig and this Garden Snail, my first this year.

Next day at Ryburgh I found a female (unfeathered) Feathered Bright Incurvaria masculella and what seems to be another Phyllobius maculicornis.

That evening I went to a concert at Snape so wasn't at home.  I put the trap on anyway and checked it the following afternoon on returning home - don't know how much more I would have found if I'd checked it earlier in the morning but there were just five moths left: Peppered Moth was new for the year, and Green Carpet, Shuttle-shaped Dart, Flame Shoulder and Nutmeg.  Also the caddisfly Limnephilus auricula.  I did at least see a Common Lizard at Aldeburgh in the morning.

On Sunday afternoon I found a few moths at Ryburgh: 4 Plain Golds Micropterix calthella, Meadow Long-horn Cauchas rufimitrella, 5 Common Nettle-taps Anthophila fabriciana and Cocksfoot Moth Glyphipterix simpliciella.  Beetles included one of the pollen beetles Meligethes sp. and Byturus ochraceus.

After this I moved on to Whitwell Common where butterflies were represented by Small Copper and Red Admiral.  Among the many Plain Golds Micropterix calthella (over 100) I found at least 3 Black-headed Golds Micropterix mansutella, a new species for me.  Sadly the sun was going in by the time I reached the spot where Dave had seen Red-barred Gold Micropterix tunbergella which would have been another lifer for me.

Other moths were Long-streak Midget Phyllonorycter salicicolella, 3 Vetch Piercers Grapholita jungiella, Common Grey Scoparia ambigualis, 2 Green Carpets and 2 Rivulets.

Beetles included a Rove Beetle Tachyporus sp. (I can't figure out how to reliably identify these to species level except using a very complex key to the arrangement of the tiny hairs on the elytra which I could barely see under the microscope) and another one that was surprisingly challenging to identify to species level (though I think I got there in the end): Malthodes marginatus.

That night Coxcomb Prominent, Least Black Arches and Treble Lines were new for the year here, with Red Twin-spot Carpet, Green Carpet, 4 Muslin Moths and Flame Shoulder.
