This must have been a good year for species to expand colonies where vacant habitat was available. Migrant butterflies have not been so numer- ous and so garden Buddleias weren't covered with Red Admirals and Painted Ladies in my experience. I only chanced on a couple of Clouded Yellows when I made a trip to the south coast of Devon at Blackpool Sands. Peacock butterflies quickly “went to bed” not long after emerging in the hot July weather. Humming- bird Hawk moths have been about but have escaped my attention. In my Chudleigh garden I had 19 species for the season as a whole which is one butterfly less than my record of 20. Large Skipper ventured in, not seen for a number of years, and I was delighted to get a Wall Brown when the species seems to be contracting to coastal localities (see page 26). This year’s Grizzled Skipper survey has highlighted a huge decrease in sites for the species (see page 10). There may be other unreported colonies in Devon so if you haven’t sent in records you have made this year for Grizzled please email Roger Bristow, County Recorder: [email protected] The more records Roger receives for any butterfly species contributes towards a more accurate knowledge of the species’ distribution in our county. Necessary record details are date, species, number, site, grid reference, your name and comments if any. We heartily recommend members to attend our Members’ Day and AGM (see page 4) which we believe will be an informative and enjoyable day. Lunch will be available if pre-booked. The day is a good opportunity to meet other mem- bers and find out more of the branch’s work. We know we could do more as a branch and if any member would like to be more active in Devon BC we certainly would welcome an extra committee member (or two!) either to take up a specific post or just help with making deci- sions and running the branch generally. Contact Jonathan Aylett our Chairman - his contact details are on page 31. We do receive requests to attend some events that we can’t always get to which is a pity, but we are limited by volunteers that are available. If you would like to add your name to the list of volunteers who help out when they can at these events please contact Mary Harold (see her contact details on page 31). Finally, the branch will embark on a programme of Winter Work tasks from this November until next March. The practical work is very satisfying knowing that sites will be improved for butterflies, not forgetting the beneficial physical exer- cise and good company! Details of tasks start on page 28. 3 Devon BC Members’ Day and AGM Sat. 27th October 2018, Crediton To be held at the Boniface Centre in the grounds of Crediton Parish Church.

The year started off with high numbers of their larvae counted on the old rail- way embankment in section 2 and was followed later by many flying adults on fine sunny days which were plentiful this year. We did several extra days’ clearance work over the winter on all four sections which helped the butterflies move more freely over the whole reserve and we are hoping to do a couple more extra work days for next winter. Many thanks to everyone who help at Lydford with the clearance work and also the weekly transects done from 1st of April through to 14th July. Winter work party volunteers needed: I am looking for more volunteers to help with clearance work this year and in 2019. I have arranged two dates: Sat 17th November 2018 and Sat 16th February 2019 if you could help out with some raking up and light coppicing, please come along and bring a packed lunch etc - tools will be provided but bring your own if you wish and I look forward to seeing you on the day. Transect help needed: I would appreciate some extra help with the transects too and if you could spare a couple of hours walking along our lovely reserve counting the beautiful butterflies in spring and summer then please get in touch (contact details page 31) and I can give you the necessary training for doing the transects. Thanks again to everyone who helps keep the Lydford reserve in tip top condition so our rare Heath Fritillary continues to thrive at the Lydford reserve.
