Disruption to footpaths at Potteric Carr

Works to connect an electricity supply from the substation on Mallard way to the iPort development (south of the M18) will start by erecting a compound in the corner of the car park at Potteric Carr nature reserve from Monday 26th June. There may be disruption to footpaths (including closures, with alternative routes) from around Friday 30th June for around 3 weeks. The works will continue across the Loversall carr part of the reserve after this, but not affecting access for visitors. The reserve will still be open, but please ask on entry for advice on areas to avoid or if any footpaths are closed.

The works will be undertaken under the supervision of an ecologist and impacts on wildlife will be avoided where possible. This work is not being undertaken by Yorkshire Wildlife Trust, but by a contractor on behalf of the iPort developers.

Moth Trapping Report for Monday Night, 19th June

Puss Moth - credit Sue & Brian Trout


The current heat wave has certainly given a huge boost to the moth recording. 102 species have been identified from Monday night’s trapping, with a few more awaiting critical examination. Last Friday night’s session boasted 3 new reserve moth records and this was repeated on Monday night with 3 more! It can’t continue can it ??

The 3 new moth records :

Schoenobius gigantella is, as its name implies, a large Pyralid moth associated with reed beds. This is believed to be only the second VC 63 record; elsewhere in Yorkshire, it’s only known from Spurn. The Potteric moth was a female.

Ptycholonoides aeriferana is a Tortricid moth associated with larch. Widespread but uncommon in Yorkshire, it is probably a wanderer from gardens in Bessacarr or elsewhere.

Chrysoclista linneella is a tiny but very attractive moth whose larval foodplant is lime. It may well have bred on one of the limes growing along the Access Track. There appear to be only 4 previous Yorkshire records, and none since 1980, so this is a significant find.

Apart from the 3 newcomers, there were a few other good moths, including the second Potteric record of Red-necked Footman; 2 Green Arches; Blackneck; Haworth’s Pug; and an astonishing 17 Coronet, a species unrecorded at Potteric Carr prior to 2014, now seemingly abundant.

Moth Trapping Report for Friday Night, 16th June

This turned out to be an excellent moth trapping session, following a very warm night. The number of species recorded (82) was similar to the previous trap night but there was a noticeable improvement in the quality of moths trapped, with an astonishing 3 new reserve records!

Most of the moths were identified on site, as usual, but a few invariably need to be taken home for critical examination. Two moths which Harry identified at home proved to be new reserve records. Pseudopostega crepusculella is a tiny, whitish moth associated with Water Mint. Rare in Yorkshire, this appears to be only the second VC 63 record of what is a nationally scarce species. Capperia britanniodactylus  is a ‘plume’ moth whose larva feeds on Wood Sage. This one is also rare in Yorkshire. Restricted to VC 63, there have been only a handful of records. This one, too, is a nationally scarce species.

The third new record, easily identified on site, was the Lackey . This species was once not uncommon in the Doncaster area but is now one of the most seriously declining species nationwide. It was good to see that it still survives in this area.

A total of 7 new species have been identified already this year, raising the overall total of species recorded at Potteric Carr to 833.

Although the 3 new moths were the stars of the show, there were some other good records, notably Green Arches, 4 Beautiful Hook-tip, 2 Cream-bordered Green Pea, Marbled White Spot, Blackneck and Figure of Eighty.

Moth Trapping Report for Saturday Night, 10th June

A mild night resulted in another excellent trapping session. The 81 recorded species included Endothenia nigricostana , a species of Tortricid with just a handful of Yorkshire records, and one which represents a new reserve record. So, this was a good find.

Marbled White Spot, Pale-shouldered Brocade, Small Yellow Wave, Epermenia falciformis and Acleris hastiana were the best of the rest.

The catch also included 3 Eyed Hawk-moths, an Elephant Hawk-moth and a couple of very handsome Peach Blossom.

Moth Trapping Report for Thursday Night, 1st June

This was another bumper catch, comprising some 77 species. There were, however, no new records or anything really outstanding. Perhaps the highlight was Cream-bordered Green Pea, a species first recorded in 1993, and with very few subsequent records, although singletons are now being seen annually.

Other moths worth noting included Marbled White-spot, now well established on the reserve; Maiden’s Blush, Figure of Eighty, White-pinion Spotted and Anania perlucidalis .

A New Moth Record for Potteric Carr

This is a rather belated report of a species of the Tineidae or "clothes moths,"
Nitidinea striolella , which was bred from owl nest-box litter on 20th April, 2017, and which is a new reserve record. Identification was confirmed by genitalia dissection. There have only been 7 confirmed Yorkshire records of this species and just one in VC63. However, it is almost certainly overlooked, as it is usually bred from bird nest-box litter and is rarely recorded in light-traps.

Thanks are due to Roger Bird for supplying the nest-box material.Ian Heppenstall
