LEPIDOPTERA
Thanks to the efforts of three contributors, a total of twenty one new moth species were added to the local list. Five were found at or near Wheelton Plantation on 31st May (four of which were "micros"). The remainder were recorded at a site in Belmont where moth trapping is done on a regular basis.
The four "micro" species were:
| Anthophila fabriciana | |
| Glyphipteryx simpliciella | (the Cocksfoot Moth) |
| Teleiodes proximella | |
| Cydia succedana |
The remaining species were "macros":
| Water Carpet | Lamproteryx suffumata |
| Chevron | Eulithis testata |
| Autumn Green Carpet | Chloroclysta miata |
| Pine Carpet | Thera firmata |
| Grey Pine Carpet | Thera obiliscata |
| May Highflier | Hydriomena imluviata |
| Scallop Shell | Rheumaptera undulata |
| Sandy Carpet | Perizoma didymata |
| Annulet | Gnophos obscurata |
| Dark Sword-grass | Agrotis ipsilon |
| Northern Rustic | Standfussania lucernea |
| Black Rustic | Aporophyla nigra |
| Rufous Minor | Oligia versicolor |
| Lesser Common Rustic | Mesapamea didyma |
| Large Ear | Amphipoea lucens |
| Scarce Silver-lines | Bena bicolorana |
Other than these new species, the two records of Hummingbirds Hawk Moths (Macroglossum stellatarum) were a highlight. Of interest also were the records of a Pale Brindled Beauty moth (Apocheima pilosaria) on 1st and 11th December (Chorley and Euxton). I believe these are the only December records we have ever had. The species normally appears in January and February.
The following butterfly species were recorded in 2000:
Small Skipper (Thymelicus sylvestris)
Recorded between 8th July and 22nd August from a total of 11 sites. It still seems to be spreading its range and is certainly more often encountered than the Large Skipper. A maximum count of 11 insects was recorded at Burgh Tip on July 11th.
Large Skipper (Ochlodes venata)
After the poorest year ever in 1999, it is pleasing to report an increase in sightings of this once common species. It was reported on 12 occasions between 17th June and 30th July.
Clouded Yellow (Colias croceus)
Between 17th August and 22nd September there were 6 records for this migrant. The maximum count was of 4 insects in flight at Adlington on 22nd September.
Brimstone (Goepteryx rhamni)
Only 4 records this year, each from a different site. This was the 3rd consecutive year that we have had the species recorded locally.
Large White (Pieris brassica)
Widely distributed and represented by many records. It was present until the 8th of October.
Small White (Pieris rapae)
As widespread but perhaps less frequently recorded than the previous species. It flew during April and May, then again from mid June until 19th September.
Green Veined White (Artogeia napi)
The two generations were well identified. The first between 1st and 30th May and the second from 7th July until the 4th of September. It was seen throughout the area, with large numbers at Withnell and Ollerton Bridge in July.
Orange Tip (Anthrocharis cardamines)
The flight time of 24th April until the 7th of June was much more typical than 1999, when first and last dates were exceptionally early. It is a well established local species found in all parts of the area.
Green Hairstreak (Callophris rubi)
Found in its usual sites at the edge of our moorland between 1st and 31st of May. We often have records of odd single insects far away from the main colonies, but not this year.
Purple Hairstreak (Quercusia quercus)
A first for the area. A single male was found dead near Common Bank Industrial Estate at the beginning of August. Another record was received from a member's garden, which unfortunately lies just 200 yards outside our area, but it proves the species occurs locally. As the habit of this species is to spend much of its time in the top branches of oak trees, it is quite possible that it has been overlooked previously. Indeed, I had an unconfirmed verbal report of the species during 1999. Needless to say, further reports will be welcomed.
Small Copper (Lacaena phlaeas)
Found in reasonable numbers in 2000. The species flew between 22nd July and 28th September with a maximum count of 10 insects at Hoghton on 14th September.
Common Blue (Polyommatus icarus)
The seven records this year - from 7 different sites - was about as good a year as we have had for some time. 11 insects were counted at Ellerbeck on 19th June, the total flight period being 17th May until 29th August.
Holly Blue (Celastrina argiolus)
Whilst no more than 2 insects were reported at any site, the species was seen from Hoghton to Rivington and White Coppice to Eccleston - a pretty wide spread! It flew from early May and then again between 26th July and 29th August.
Red Admiral (Vanessa atalanta)
As usual, I received more records of this species than of any other. It was frequent between 13th June and 29th October with large numbers reported at sites in Rivington, Brinscall and Withnell.
Painted Lady (Cynthia cardui)
2000 was a much better year for this migrant. It was seen only 4 times in June but from 8th August until 17th October it appeared in most parts of the area. As many as 7 were seen together at Belmont on 4th September.
Small Tortoiseshell (Aglais urticae)
Another poor year for what used to be a much commoner species. It was infrequent in the spring with only a handful of records in April and May. From 19th July until 19th October it occurred throughout the area but never in great numbers.
The Peacock (Inachis io)
As has been the case for a few years now, this species was the commonest Vanessid in spring. It was seen quite frequently between its appearance on 18th March until mid June. Its summer generation was in flight from 22nd July until the 13th of October. Large numbers were reported near Dean Wood, Rivington, and at Belmont during August.
Comma (Polygonia c-album)
A couple of appearance during spring (19th April at Belmont and 30th April at Rivington) suggested it might not be a good year for the species. However, the summer generation did us much better. From 11th July until 27th October it was recorded at many sites. I notice that we received no records from west of Euxton. It seems unlikely that it does not visit the gardens of Croston, Eccleston and Mawdesley. Records would be welcome.
Speckled Wood (Pararge aegeria tircis)
In total, records were received from 29 different sites representing most parts of the area. Up to 10 insects at a time were reported. Its continued expansion is very pleasing. The flight time was 8th May (Birkacre) until 13th October (Rivington).
Wall Brown (Lassiommata megera)
The spring generation was on the wing between 21st May and 18th June. The late generation was much more often reported as is usual for this species. Its flight period was 22nd July until 25th September.
Gatekeeper (Pyronia tithonus)
The species is well spread in the area but oddly no longer reported to the west of the area, which was once its stronghold. I feel this is more likely to be a lack of recorders rather than a lack of insects! Records were received between 30th June and 28th August. The largest numbers (over 100) were reported from Birkacre on 30th July.
Meadow Brown (Maniola jurtina)
Reported from 17th June throughout the summer until 28th August. It is common especially to the east of the area. Highest numbers were from Belmont (200+ on 20th July) with good numbers again from Birkacre and Burgh Tip.
Small Heath (Coenonympha pamphilus)
After the worst year ever last year (1 record only) the four records in 2000 should be a cause for celebration!. It is found to the east of the area in June and July and I would be very grateful for more records of this one.
ODONATA
There were no new species added to the local list this year. The main points of interest were the records relating to the Emperor Dragonfly (Anax imperator) and the Emerald Damselfly (Lestes sponsa) at Cuerden Park. This is the second year of good records for these species which hopefully will now be firmly established.
Species recorded this year were:
ZYGOPTERA (Damselflies)
Banded Demoiselle (Calopteryx Splendens)
Records for Cuerden Park between 16th June and 30th July. 11 records in total with good numbers reported..
Emerald Damselfly (Lestes sponsa)
7 records this year. 5 from Cuerden between 12th July and 4th September, a record of breeding at Belmont on 12th August, plus a single record from Healey Nab on 13th August.
Large Red Damselfly (Pyrrhosoma Nymphula)
Recorded from 11 sites between 6th May and 18th July.
Blue Tailed Damselfly (Ischnura Elegans)
Recorded at 6 sites between 14th May and 4th September.
Azure Damselfly (Coenagrion Puella)
Disappointingly only recorded at 3 sites (Belmont, Cuerden and Euxton) between 10th June and 4th September
Common Blue Damselfly (Enallagma cyathigerum)
Recorded at 5 sites between 18th June and 4th September
ANISOPTERA (Dragonflies)
Southern Hawker (Aeshna cyanea)
Just three recorded this year. The first from Withnell on 6th August, the other two from Brinscall in September.
Brown Hawker (Aeshna Grandis)
Recorded throughout the area as usual. First date 7th July and last 21st September.
Common Hawker (Aeshna Juncea)
13 sites from 18/7/00 to 1/10/00
Emperor Dragonfly (Anax imperator)
Seen at the ponds in Cuerden between 7th and 19th July, and present at Belmont on 29th and 30th July.
Four-spotted Chaser (Libellula quadrimaculata)
4 sites. From 7th to 30th of July.
Broad-bodied Chaser (Libellula depressa)
After two blank years, it was pleasing to receive a record from Limbrick on 13th June
Black Darter (Sympetrum danae)
Only seen at three sites in 2000. 22nd August to 29th September. 100+ recorded at Belmont on 3rd September.
Ruddy Darter (Sympetrum sanguineum)
Single record at Cuerden on 11th August.
Common Darter (Sympetrum striolatum)
12 sites from 19th July until 17th October. As many as 10 insects were recorded at Rivington on 23rd August.
