26th May: Field Trip
9 Members defied the gloomy weather forecast to embark on our 2nd. Field Trip of the season. It was good to have Jane Ostler amongst us as she was instrumental in helping me set up our BC Reserves here with the Forestry Commission when she was working for the then Nature Conservancy Council (now Natural England) about 30 years ago!

We went by the usual route on foot into the wood, and around in an anti-clockwise direction, visiting both the Sanctuary and Glades BC Reserves and the broken concrete runways and tracks in between. We payed particular attention to the excellent habitat at the edges.

The sun actually shone in brief episodes when it was warm, but mostly it was bright but cloudy with a stiff breeze. There were a few light, but thankfully short, rain showers,

We were pleased to find all the rarer target butterfly species, and some in good numbers, but many common species failed to show themselves. 

Recording was undertaken for each site, sub-site and area for our Recording Schemes, but for the purposes of this brief Report the totals of the species seen were;



Grizzled Skipper      33

Dingy Skipper          38

Green Hairstreak       1

Common Blue          33

Brown Argus              4

Small Copper             3

Small Heath             12 

Speckled Wood         1

Green-veined White  1



Burnet Companion     3 

Cinnabar                    3 + sev larvae

Latticed Heath            1

Burnet Moth larva       1


Common Spotted Orchid - several

Dyer's Greenweed - large clump

Devil's-bit Scabious - several. groups

Alan Armstrong reports.......Absolutely loved it here. Was hoping to see Grizzled Skippers and was not disappointed. Saw dozens!!

A great little butterfly that I had only seen once before. Also saw numerous Dingy Skippers, as well as Brown Argus and Common Blues. Also heard 2 cuckoos.


I also enjoyed the historical aspect of the place. Those huge runways and their role in the Normandy campaign. I will go back there every Spring now. I am a member of the East Midlands butterfly conservation group, but I am very impressed with the Lincs. branch.

24th May:

George Pears reports.......

Good turnout on this intermittently sunny day at Twyford. Butterflies spotted were the Brown Argus, Common Blue, Green-veined White, Orange-tip, Dingy Skipper, Grizzled Skipper and the Small Copper. Moths included the Treble-bar, Cinnabar, Mint, Cream Wave and the Green long horned moth. Hundreds of moth caterpillars found included those of the Mottled Umber, Blood-vein and the Pale Brindled Beauty among a few other (as of yet unidentified) species.
