Upcoming moth-ing event at Llanymynech Golf Club, Saturday 24th May.
Tuesday, 20 May 2025
A moth night at Cultivate, Y Drenewydd. Friday 16th May 2025.
A second invite from Cultivate, Newtown (next door to Theatr Hafren) for me to run another moth night at their fabulous community gardens, proved to be a chilly challenge and not of the hot variety!
With the setting sun, a fabulous evening meal prepared by Annie Levy was provided for attendees, using on-site produce and Newtown food hub ingredients, a major part of Cultivate's sustainability ethos. Locally grown and reduce waste https://www.cultivate.uk.com/bwyd-powys-food/
By switch-on time for the traps, around 9.15pm, it was apparent that the forecast cloud was not going to materialise and a steady drop in temperature was felt by all.
Having caught and examined Common Carpet, abundant Alucita hexadactyla and Gracillaria syringella before dusk, the recording base moved indoors as darkness descended and the familiar chill deepened.
Initially, micro moths easily outnumbered their macro counterparts, including Hedya pruniana, Anania hortulata, Bactra lancealana and Tinea Trinotella, the latter being a specialist of bird nests. A lovely Cinnabar and Silver Y were the next macros brought to the table. We then saw a slowly-but-surely flow of diverse macro moths, including Figure of Eighty, Miller, Poplar Hawk-moth and Pebble Hook-tip.

Cors Dyfi Moth Night, 26th April 2025. Report by Simon Spencer.
Our first MMG evening moth event at Cors Dyfi on Saturday 26th April was very successful. It is a superb venue being surrounded by excellent and unusual wetland habitat, having electricity, tables and warm shelter if needed. Our hosts Dulcie and Tom Faulkner were very welcoming and regularly trap there. Phil McGregor, Simon Spencer and Richard Bullock attended. We were joined later by Peter Williams, Mont Moth Recorder. We started by putting traps along the board walk where we heard Grasshopper Warbler, Cetti’s Warbler and Sedge Warbler. We ran a Mercury Vapour trap in the car park and a white Sheet with a MV bulb by the picnic tables. The weather was kind with cloud coming in from the West keeping the temperature up. I am sure it was still 12C when we packed up at midnight. It was a very enjoyable evening and we got some stunning moths.

BIS Library Loaning Scheme
Hi all,
I thought it worth advertising this very good lending scheme from the Biodiversity Information Service as it applies to the whole of Powys and includes the loan of moth traps!
Phil.
BIS Library Loaning Scheme
We are excited to launch the BIS Loaning Library which will be made available from the end of this month to all recorders or wildlife enthusiasts across Powys. Through the library, we want to inspire recorders to generate new biological records and enable anyone with an interest in wildlife to learn more and develop new skillsets!
As part of the library scheme, you will be able to borrow:
- Guides and books on various taxon groups
- Hand lenses
- Moth traps
- Camera traps
- Microscopes
The library is open to recorders of all abilities who are live in Powys. We can make arrangements for recorders to collect loaned equipment/resources from our Brecon office or somewhere more convenient to you.

An Autumnal evening in Gerddi Bro Dyfi, Machynlleth
All was set up & the lights were on by the time Mark & I arrived in the gardens, behind the Plas in Machynlleth. And there were already a number of people there eager for the traps to start yielding their moths. The first record was a Brimstone Moth, and in face it was one of the more numerous moths of the night.
As well as moths there was a good showing by other invertebrates, including some magnificent crane flies, lots of pesky caddis flies pretending to be moths, and a very handsome beetle. One keen person managed to pot up a sleeping Large White Butterfly as well.

We had a very rare but welcome sighting of the county moth recorder, Peter Williams. It was a great pleasure to see him at an event again, and it was lovely to be able to hand the pots of moths to him for an instant ID. Especially as I managed to completely mis-identify the Udea ferrugalis (Rusty-dot Pearl) as a Straw Dot! In my defence the light wasn't very good.....
Phil was kept very busy through the night, taking groups round to all the traps. He also stayed long after the last of us had started to head home. Many thanks to him for organising and setting up an excellent night, and to Fern Towers for allowing Montgomeryshire Moth Group to trap in the gardens. It is always a very warm welcome there. In total we trapped 15 macros & 6 micros (plus one butterfly). The full list of moths can be found here.

Butterfly Conservation Wild Spaces project.
Butterfly Conservation have a relatively new project entitled "Wild Spaces". No doubt some of you are aware of this already.
The idea behind this project is to engage people, groups and organisations in creating room for nature to help stem the decline in species, focussing on Butterflies and Moths. From balconies to parks, gardens, schools and work place grounds, no space is too small or too large. BC have pledged to achieve 100,000 of these Wild Spaces by 2026, a very ambitious but possible target.
Attending a BC branch meeting yesterday (28/09/2024), where this project was more formally promoted, it really struck me as a positive and worthwhile project that anybody can sign up to, even if you have already created a wild area. It is good for nationwide environmental charities to know about these, to build a picture of awareness and action. Where it is happening and not happening.
On the BC website map which roughly shows where all the pledged Wild Spaces are, Wales is terribly lagging behind and the message needs to be spread. Montgomeryshire has only a few places pledged when I know of dozens myself. This is the link to the project where you can read more about it and sign up https://wild-spaces.co.uk/ Please do so if you can and encourage others to do likewise. It does not cost anything. It will not result in clip-board visits!
Many thanks,
Phil.

Butterfly Conservation - Butterfly Emergency
This in effect applies to moths too, they feed on many of the same poisoned flowers/plants, just at night:
Call on the Government to take urgent action.
Wondering where all the butterflies have gone? You're not alone.
In 2024, we've seen butterfly numbers fall across the UK. With 80% of butterflies having declined since the 1970s and a third of moth numbers having fallen in that same period, the time has come to tell the Government enough is enough.
We're calling on the Government to:
- Declare a nature emergency
- Implement an immediate and permanent ban on butterfly-harming neonicotinoid pesticides, without exceptions.
If you agree, sign our letter and join leading conservation figures in calling on the Government to take action now.
This is the link to the letter:
Phil.
