A few insect offerings from Sun Beck

Following yet another potential nights moth trapping thwarted by heavy rain I made use of the morning sun to have a walk around Sun Beck wood, Brafferton.  My quest for putting in the effort to see  species other than birds and moths really paid off and several new insects were noted.  

There were dozens of these bright yellow sawflies, but this one allowed close approach, enough to identify it as Turnip Sawfly.

A rather subdued wasp that was initially lying on its side in a buttercup eventually dragged itself to a more photogenic pose.

Several beetles were seen including the diminutive yellow and black 14-Spot Ladybird, and the dark form of .a click beetle Denticollis linearis.

There were at least 15 small shieldbugs which I did not recognise, assuming they were early instars of a more common species.  On checking the photos on return it was plain to see they were all adult Woundwort Shieldbugs, another new species for me and right at the northern edge of their range.

Eysarcoris venustissimus (Woundwort Shieldbug)

A very small insect with intricately patterned wings made identification rather difficult.  Having initially offered it for identification on the Diptera forums I was quickly dispatched by the resident experts to look at Hemiptera.  A peruse in that direction it was clear that it was actually a lacehopper, probably Cixius nervosus.

It was inevitable that several moths were seen, including a Nemaphora degeerella which eventually settled, and the diminutive Micropterix aruncella, a moth I have only seen twice before.  Other moths seen were a Celypha lacunana and a Silver-ground Carpet.

As a footnote, while looking through photos from previous years for any unidentified species threw up a bug from 2015 that with a quick search proved to be a Tree Damsel Bug, a southern species at the northern edge of its range.

A few odds and ends

With moth numbers reported by many as still being very low I have made little effort to spend nights out for such little return; we are obviously still in the big 'dip' between the Orthosias and the early summer species.  However, daytime walks have proved very rewarding with manageable numbers of new species to find and identify, as well as some fantastic scenery.

Up and running again

Following the usual early part of the year hiatus it only takes a few decent days weather and the first flush of Spring growth to get me going again! 

Despite my best intentions to look at other things besides moths in the last few years I have only scratched the surface.  In an effort to broaden my experience I have spent the last few months looking into and planning which species to look for and places to visit.  To start with as a frivolous attempt of setting goals I created my British Pan list (not cooking implements...but a list of all living species identified.).  The bulk of the list was made up by moths and birds, a modest list of plants and small numbers of other species and came up with just over 2000 species in the UK.  This is a small number compared with the top Pan listers who claim well in excess of 10000 species.

To kick-start my efforts I booked a number of themed walks, botanical visits to Arnside, Silverdale and N Y Moors, and an insect course at Ainsdale.  The first of these was just over a week ago at Arnside in Lancashire, fantastic scenery, welcoming attendees, great weather and a reasonable list of plants.  It was a pleasure to have the experience of various experts and a lack of pretentious one-upmanship.  The only downside was one of the target rarities Teesdale Violet was not in flower, but many of the other more common species more than made up for it.

Even though some of the species were common I still amassed over 40 new species to me.  The list included lichens, ferns, mosses as well as flowering plants and shrubs.

It was such an enjoyable day that I am really looking forward to the next trips, and a casual look over the last few days has added several more common species.

Back to the last few days and the fantastic weather has got me out and about....at night, three on the trot.  Two nights at the private site at Brafferton Spring followed by last night under the aspens at Pilmoor.  Modest numbers and up to 23 species with several new for site at Brafferton: Red Chestnut, Grey Shoulder-knot, and a cracking micro which at first glance looked fairly indistinct.  However, once photographed its subtle pale green colouring and markings revealed it as Acleris literana which is a rare oak-feeding moth in North Yorkshire.  The awful modern common names given to micro moths names it as Lichen Button, not a reference to its food plant but more to its appearance.  Don't get me started on common names....

A look back at 2018

If I thought 2017 had been good then 2018 has been outstanding!  I achieved my best year total of species identified and I had 60 (!) new lifer moths in total, seven of which were outside of Yorkshire.  In Yorkshire alone I had 65 moths for the first time in the County, 12 of which I had seen elsewhere before, mainly southern species making their way northwards.  Once again leaf-mining micros made a sizeable contribution to the total, but seven new Yorkshire macro moths were of note including three not identified anywhere else before.

The first highlight of the year was a planned foray to Lancashire to try and see Belted Beauty, a very rare moth in one of its main English sites, and was lucky enough to find this fine male.

In May through to mid June I concentrated on leaf mines on birch leaves in particular looking for Eriocrania mines, a small family of mainly birch feeders, very few of which recorded in VC62.  My aim was to find at least one salopiella mine acceptable as new to VC62, following two probable vacated mines in previous years, both in early June.  I managed to find a total of twelve E. salopiella mines at four sites at Pilmoor, Sessay and Brafferton, 13 - 26 May.  Other birch feeding miners were seen in the same area as a result: two E.unimaculella, 7 - 13 May; two E.sparmannella, 24 June - 2 July; eight E.cicatricella, 7 -20 May; and finally 59 distinctively grey larva tenanted mines of E.sangii.

 

Clockwise from top left: unimaculella, salopiella, sangii tenanted mines and a cicatriella larva.

                                                                       

As a further consequence of looking at leaves I found at least 18 Heliozela sericiella mines on oak at Brafferton, following the first VC62 record I had belatedly identified from an older photo at Pilmoor.  The larvae mine from the petiole out through the main rib, cut an oval hole off the midrib and drops to the ground to pupate.

My use of trapping sites was rather more limited than in recent years mainly due to focussing my attention from early May to a new private woodland site, Brafferton Spring (VC62).  This site is just east of Helperby, and is loosely associated with my sites at Pilmoor and Sessay.    From early May I spent  a total of 21 nights trapping at Brafferton Spring using a 125w MV on a Robinson trap and a 160w MVB over a white sheet, and at least a further 14 day visits looking for mines. In just six months trapping at this new site I amassed a total of 325 species which is not at all bad considering the lack of Spring species.

 

The highlights from Brafferton included at least three new VC62 records: the leaf-mine of Eriocrania salopiella already mentioned, and adults of Dioryctria sylvestrella and Epinotia signatana both of which have been accepted, and a first record since 1868 of Nemapogon clematella.

Other highlights from Brafferton included my first Devon Carpet away from its very few upland breeding sites in the County, a total of 11 of the scarce Pine Hawk-moth, two rare Wainscots, Mere and Twin-spotted, and the first Dog's Tooth probably for twenty years.  Remarkably the Devon Carpet, Twin-spotted Wainscot and the Dog's Tooth all occurred on the night of 3rd August along with several others scarcities.

In the autumn I targeted more leaf-mine species and again this proved very succesful.  New to VC64 was mines of Ectoedemia sericopeza on the samara of Norway Maple in Boroughbridge, and hundreds of mines of Ectoedemia argyropeza on aspen leaves at four sites in the Boroughbridge (VC64) and Pilmoor and Brafferton area, with only one previous unpublished VC62 record.

So then, what about 2019?  I think I will be targeting some of the less well covered parts of the County in the far west and especially some of the moorland moth species, and also try my hand at a few of the other insect families and plants.  So much to see but I don't think I will be achieving the same number of new moths for the year!

Alder Leaf Beetle

A line of alders at Pilmoor (VC62) were noted as being totally decimated on 15 September 2018 by what appeared to be at least 100 small shiny beetles. Having seen a similar photo on the internet I was alerted to the fact that they were Alder Leaf Beetles Agelastica alni, that were considered extinct in the UK until 2004, when they suddenly reappeared in Manchester presumably as an accidental import on alders.  It has since spread to Lancashire, South and West Yorkshire and also appeared in Hampshire.  On checking my records my first photos of the culprit were taken on 20 August 2018.  The first photo below is a slightly out of focus phone photo but does indicate the scale of the damage to the alder leaves. I do recall seeing them here in at least one previous year (probably 2017) but despite looking through my photos I cannot find any evidence.

On sending the record to the YNU Coleoptera Recorder he was kind enough to advise me of the current distribution in the Yorkshire database, and so it would appear to be new to VC62.
