Recording Butterflies in Your 1km Patch

Filed under: Butterflies — Tags: , , , , — Scott Shanks @ 11:12 pm

Do you currently record butterflies in your garden or around your neighbourhood? Perhaps you’ve fancied taking part in one of the branch butterfly surveys but the sites were all too far away or took up too much time with repeated visits? If so you might be interested in the ‘My Patch’ recording project which aims to discover more about the butterfly species in Your local area. It’s not hard work and gets you out of the house with a purpose. By doing a ‘patch’ it means you wander anywhere you can access within a 1kilometer square. Go out as often as you like, for as long as you like – just get out for a walk and simply jot down the date and what you see.

Your ‘patch’ can start right outside your front door if you like. Even by walking through housing areas, glancing in allotments, hedges, spare land, scrubby areas, river banks etc. you can usefully record areas which will otherwise be blanks on the County records map. Others might prefer to get in a car or on a bike and do a ‘patch’ a couple of miles away, you know, that bit you’ve always thought looks good but never quite got there to have a good look.

 

If you fancy the idea, and there really is not any more to it, get in touch with me and tell me the ‘patch’ you want to do or let me know where you are and I’ll suggest a ‘patch.’ I need to know before you start because somebody else might already be doing the bit where you are. Just use footpaths, roadside verges or areas with open access as we don’t want you being frog marched out of anywhere or having to run like the clappers with a bull halfway up your shirt tail! Go on, give ‘patches’ a go – adopt a 1km square as your own.

The scheme was launched last year in the Cumbrian branch area and Steve Doyle of the Cumbrian Branch reports great success, with many folk there wanting to do the next 1km square too! It’s always the same, when you get to the boundary of your square, the next bit looks interesting too!

You can either e-mail or post me your records at the end of each month or all together at the end of the year and I’ll pass them onto the correct Butterfly Recorder for your area and ensure that all your records get passed onto the National Butterfly database. There is a recording form that you can use to keep track of your records.

Transect recording has been the key method of recording thus far and will continue in the future as it is a very valuable source of repetitive data from which trends emerge. We can use the information gathered from these trends to see how well butterflies are doing across the country and can also tell if management action needs to be taken at the transect site to protect the species there.

Some regard transects as rather formal however and are not so willing to commit to walking a transect once a week. Even so, despite formal transects and other valuable ad hoc records there were still a vast number of blank unrecorded or under-recorded squares (even in towns and cities) in south west Scotland. This is where the ‘Your Patch’ recording project can help.

If you already send in your casual/ ad hoc records from day trips and walks please continue to do so as you are contributing vital information for research into butterfly distribution.

The My Patch recording project will hopefully highlight areas in our cities, towns, villages and the countryside where butterflies are thriving, squares with lots of species or those with high numbers of a particular species. This information can be used by local councils managing our green spaces or community groups keen to encourage biodiversity or land owners keen to manage their land with wildlife in mind.

South West Scotland Butterfly ‘Patches’ – General Guidelines

  1. If your square covers an area where you feel threatened or in danger, don’t do it. Report back to me and we can agree a different one.
  2. No need to stick to the same route in your square every time. Go everywhere within it that you can. Your square is at most 1km long so it is not a long way from one side to the other.
  3. Best times of day to record are 10.00 until 16.00 but beyond that in a very warm spell and provided the weather is fine.
  4. Remember different species fly at different times of the year so visit regularly or at least once a month.
  5. Walk at a slow steady pace, lingering in likely places, watching for movement.
  6. Not all species fly at eye level or below. The Purple Hairstreak is very under-recorded in  South West Scotland. The Purple Hairstreak is undoubtedly more widespread, so in late afternoons in July and early August pause and look for movement at the top of oak trees. If you see ‘silver coins’ flitting around they are likely to be Purple Hairstreaks which rarely come to ground.
  7. If you have difficulty telling different species apart, let me know and I will get some help for you.
  8. Complete your form during your visit or immediately after. Don’t leave it too long.

 

My local patch is in the west end of Glasgow. Grid reference NS5665.

It’s not the greenest area with few gardens containing flowers, but it does include a great bit of rough grassland and wildflowers in Yorkhill Park (behind the children’s hospital) where I’ve seen 9 species! The most important thing is that I walk through parts of this square at least once a day. I’ll likely also do the square to the north of it NS5666 too, as I walk through this on the way to work almost every day (and it has a bit more green areas and potential habitat!).

Moth Records for VC98 Argyll Main

Filed under: Moths — Tags: , , — Andrew Masterman @ 11:04 am

Vice County 98 covers Argyll south of Loch Leven and north of the Crinan Canal near Lochgilphead, the Cowal peninsular and Glencoe, most of Rannoch Moor and the islands of Lismore and Kerrera.

As of February 2010, there are 22958 Macro-moth records in the VC98 database relating to 331 species. Eighty-six per cent of these records relate to the Glencoe Rothamsted trap at the National Trust for Scotland visitor centre. The Rothamsted Light Trap at Glencoe is part of a UK wide network of 80 traps run by the Rothamsted Insect Survey since 1968.  The Glencoe trap has been in operation since 1996 and the addition of the data from this trap added many new species to the VC98 database. There were 62 new species which are classified as common species. There were a further 28 species which have much more local distributions and are interesting records.

As of February 2010, there are 191 Micro-moth records in the VC98 database relating to 62 species.

Six UK BAP Macro-moth species are present in the VC98 database.

Barred Tooth-striped  (Trichopteryx polycommata) has 27 records relating to five sites in north Argyll. This moth has very localised scattered distributions in Scotland and England with the majority of Scottish records in Argyll.  It flies early in the year in March April and comes to light traps. The larvae feed on Ash or Privet and it overwinters as a pupa. In Argyll, it has been recorded at Creagan Wood and Glasdrum NNR on the north side of Loch Creran, on the south side of Loch Creran at Barcaldine and also at Glen Nant NNR. There is also one record at the Glencoe RIS trap. These are all deciduous woodland sites but in southern England, it is associated with open scrub on chalk downs and with some limestone sites south of Cumbria.

Argent and Sable  (Rheumaptera hastata) has 16 records relating to 12 sites in north and central Argyll. This is a day-flying moth on the wing in May and June and the caterpillars feed on bog myrtle and birch and it overwinters as a pupa. There are three sub-species in the UK with hastata hastata occurring in England and southern Scotland as far north as southern Argyll, a smaller and darker form,  f. nigrescens found in the Hebrides and the far NW of Scotland and a third sub-spp hastata f. laxata which occurs in Argyll and other parts of the southern Highlands.

Square-spotted Clay  (Xestia rhomboidea) is an ex-UK BAP species and has 15 records relating to 4 sites in north and west Argyll. This is a rare species in Scotland with most records from Argyll although it is much more common in southern England. If flies in late July and August and comes to light. There is some uncertainty about which plants the caterpillars feed on but birch and bramble are likely examples of a range of plants which can be used. It overwinters as a small caterpillar. The habitat is deciduous woodland and in Argyll, it has been recorded at Glasdrum Wood and Glasdrum NNR, Glen Nant NNR and Taynish NNR all of which have mature decidious woodland and also around the Loch Melfort area.

Forester (Adscita statices) has 22 records relating to 8 sites on the west coast of Argyll. It is a day-flying moth which is a joy to see with its bright emerald shiny wings. Its caterpillars feed on Common Sorrel and Sheep’s Sorrel and its habitat in Scotland is sunny sheltered  areas with some bracken in coastal parts of Argyll.

Narrow-bordered Bee Hawk-moth  (Hemaris tityus) has 50 records relating to 24 sites mostly in north Argyll but there is one for the southern tip of Bute in the south of Argyll. This is an amazing day-flying moth found during late May and June in the same areas as Marsh Fritillary. This is no co-incidence as they both have the same foodplant, Devil’s Bit Scabious and the same flight period so it is possible to see both these rare species of Lepidoptera at the same site on the same day! The habitat of both these species is low lying flat  damp grassland, sometimes a more heathy type habitat,  with abundant Devil’s Bit Scabious but the bottom of slopes which also tend to be damp may also provide good habitat.

Transparent Burnet (Zygaena purpuralis) has 25 records relating to six sites near Oban. The strongholds of this amazing moth are the Hebridean islands of Mull, Skye, Ulva, Eigg, Canna, and Rhum and the only records on the mainland are around Oban and also in parts of Kintyre. It was seen on the islands of Kerrera and Lismore in 1960 but there are no recent records. The adults are day-flying in warm sunshine from early June to July and the caterpillars feed on wild thyme. It overwinters as a caterpillar. Its habitat is steep, heathy and grassy south and south-west facing slopes and under-cliffs near the coast.

Recording and Monitoring Butterflies and Moths in South West Scotland

One of the most important aspects of conservation is the recording and monitoring of our native species. Monitoring a species over time allows us to determine whether the population is declining or increasing, and also provides data on the distribution of a particular species and whether they are increasing their range or becoming extinct at previous strongholds.

Small Tortoiseshell Survey

Small Tortoiseshell Survey

 

There are a range of ways in which you can get involved and I’ve listed a few below.


1. Monitoring specific species of Butterfly
The branch is looking for volunteers to help with species-specific surveys targeted to some of the most threatened butterfly species in Scotland. Participating in butterfly surveys is fun, informative and very rewarding. Plus it’s a great way to see some of the
UK’s rarest species. It involves a wee bit more than just counting butterflies as we also need to know a bit about the plants which comprise the habitat and the overall condition of the site.  To help conserve the UK BAP species in Scotland which are currently under threat, we need to revisit historical sites to see if the butterfly is still there and also to identify sites where the habitat has deteriorated and is a threat to the survival of the butterfly colony. These sites can then be flagged up with Butterfly Conservation, Scottish National Heritage and LBAP partners with the aim of getting appropriate management work done to improve the condition of the sites. This survey potentially requires only a single visit to a site (although return visits can help gain more data), and therefore you can choose to visit as few or as many sites as you wish. Every piece of information you collect could be immensely useful.
Surveys for the Chequered Skipper, Dingy Skipper, Pearl-bordered Fritillary, Mountain Ringlet, and Northern Brown Argus are detailed on the branch website:
http://www.southwestscotland-butterflies.org.uk/index.shtml
 
2. Monitoring specific sites looking for butterflies
There are two ways that volunteers can help monitor butterflies and moths at particular sites.
2a. The first is the Butterflies of the Wider Countryside Survey.
This is a research project collecting data that can be used to monitor the abundance of butterfly species across the countryside. It involves only 2 visits to a particular site, once in July and once in August, but further optional visits in May and June would provide more data. The sites are all 1 km map squares that have been chosen randomly to provide an unbiased assessment of butterfly abundance in the countryside. The methodology involves walking across your
1km square twice in as straight a line as possible counting all of the butterflies that pass near to you. You can record others that are further off your route separately, but for the study you need to only record those that come within 5m of your position as you move along the route. This survey is being tried in our branch area for the first time during 2009 after trails in England and up in the Highland branch area of Scotland.
For more information on sites to be surveyed in the branch area and more on the methodology see
http://www.southwestscotland-butterflies.org.uk/surveys/wider-countryside-butterfly-scheme-2009.shtml
and
http://www.ukbms.org/wcbs.htm
 
2b. The second type of site-specific survey is a Butterfly Transect.
This survey monitors butterflies on a set route through a particular site over the course of the Summer. The methodology requires one visit each week between April and September. The recorder takes a note of all butterflies that pass within a
5m by 5m ‘imaginary box’ in front of them as they walk along the route. It provides a wealth or information about the butterfly population on that site and can give an early warning of population declines, as well as providing data on when species are on the wing each year. There is a network of monitored transects (normally in nature reserves or on sites where threatened species are found) that are co-ordinated by the Centre for Ecology and Hydrology, but anyone can set up their own independent transect in their local park or along a canal footpath where they regularly walk with support from Butterfly conservation. A group can share a transect, which helps cover holiday weeks etc. For more information see. http://www.southwestscotland-butterflies.org.uk/transects/index.shtml.
 
3. One of the easiest ways to record butterflies is to send in casual records of butterflies you see when out for a walk, or in the garden. Every sighting is useful to build a picture of the distribution and abundance of all the species throughout the country. Each record requires a few details for it to be useful: The recorders name and address, the date, the species of butterfly seen, the number seen, and the location with a grid reference. A recording form is available here at http://www.southwestscotland-butterflies.org.uk/butterfly_records/index.shtml. All records are passed onto the national Butterflies for the New Millennium scheme organised by Butterfly Conservation and will be used to create distribution maps that can track changes in butterfly distribution throughout the country. Every county in the UK is covered by the recording scheme, so please keep a note of any butterflies that you see when on holiday too.
A good description of how to work out a grid reference can be found here:
http://www.butterfly-conservation.org/text/65/instructions_for_recorders.html
 
 
4. South West Scotland is home to a large number of Moth species. Moth recording is an important part of Butterfly Conservation’s work. There are many varied species of moths throughout SW Scotland and it is well worth spending the time to study them. The National Moth Recording Scheme was set up in 2007 to provide a national database for macro-moths in the UK. This is a major step forward for moth recording in the UK. The branch area contains a number of moth species that are declining, rare or extinct in other parts of the UK, with over 854 species of macro-moths recorded in the branch area so far.

Conservation work is currently underway in the branch area to preserve the habitat of endangered burnet moths on the West Coast of Scotland. However you don’t need to travel to remote areas to record moths and provide useful data. You can record moths found in your garden using a light trap or a technique called wine/sugar roping to attract passing individuals, but even records of moths that come to your kitchen window could be very useful!

The branch has a number of moth traps available for members to borrow so they can have a go at light trapping, and a number of moth trapping events are run each year where you can come along and get an idea of what it’s all about (see events page on the branch website). There is also a network of vice county moth recorders throughout the UK, who collate all of the moth records in a particular county and who would be more than willing to help you with identifications and offer advice on how to get started. There is also a Yahoo group for Scottish moth recorders where members can post details of what they’ve caught recently or ask for Id help. We are luck enough to have some fantastically knowledgeable and experienced moth recorders in Scotland willing to help beginners get started. http://tech.groups.yahoo.com/group/ScottishMoths/

For more information on recording moths and details of free training courses see the Moths Count website at http://www.mothscount.org/site/index.php?option=com_frontpage&Itemid=1

Please get in touch if you’d like to take part in any of the surveys, try moth trapping or set up your own transect and the committee will be glad to help with any questions and advice. If you’d like specific training for any of the recording schemes or just want to discuss your ideas, please get in contact and we’ll do are best to help you.

Best wishes and happy recording in 2009!
