First I should clarify the title of this post. I have not recently changed sex and given birth, and I am not having an American potty-mouthed rant. Mother should, of course, be pronounced moth-er. I suppose it was natural for the term birder to be paralleled by mother.
But I do have something to confess.
When I first started to develop my interest in birding, forty plus years ago, I took it very seriously. I spent ages reading through the largely rubbish field guides we relied on in those days, I took the time to painstakingly learn and remember birdsong, and through the whole course of my birding life, as many bird calls as I could. So theoretically if a new bird was to land in front of me I would have a good idea of what it was, and how rare it was.
My moth journey has been very different. The impetus came when the first moth book was published which showed moths in their natural resting positions. A Field Guide to the Moths of Great Britain and Ireland, followed by its sister Field Guide to the Micro-moths of Great Britain and Ireland made me realise I could do this. I bought a moth trap in 2018.
I quickly realised there were an awful lot more moths than birds and I needed help.
My first mentor was John Sirrett and, bless him, he spent every week of that first year studying my terrible photographs and talking me through the identifications and misidentifications I had made after hours of staring at my books. I also realised there were on-line references that could be tapped into, and I found the Nature Spot website (which strictly speaking covered Leicestershire) very helpful.
Within a year or so I was able to give John a break when I discovered Twitter. An on-line Moth Identification UK guru (Sean Foote from Hampshire) willingly answered everyones queries. I relied on him for the ones I wasn't sure of.
Then about four years ago AI appeared. Someone put me onto the app Obsidentify, and I let that take the strain. Mind you, as I got more experienced I came to realise that it wasn't completely reliable. A poor photograph, or an "odd" moth would produce a misidentification. But it was so much quicker than looking through books or posting your photos and waiting for the expert to post his identification back.
So now I've become lazy. I've never been particularly interested in trapping away from the garden, and every year still brings new moths with remarkable regularity. I really like the fact that as I open my trap I can find myself staring at a moth which I have literally no idea about.
Which brings me to this morning.
The first notable moth did ring a bell. And it was gorgeous. I had previously caught a Gold Spot in my first year of mothing, 2018, but had not seen a single one since.
I technically didn't need Obsidentify, but I've become addicted to the security blanket it provides so I pointed my phone at it anyway. Identification confirmed.
So I picked my way through the rest of the catch. The really familiar ones I just named, the less familiar I Obsidentified for reassurance. Some moths catch me out every year. I find a Straw Underwing in the trap every year, but it never seems to ring a bell.
But generally I do recognise the macro-moths. Not so the micros. There are a core of regulars I'm happy to wave through, but many are a challenge. Obsidentify also struggles more with micros, but its pretty good and I use it a lot (if only to remind myself what the moth I'm looking at is called).
This morning two micros in particular looked unfamiliar. The first was this one:
Obsidentify had no doubt. Neocochyllis molliculana it told me. New for the garden. I should have put it in a pot, but being lazy I didn't bother. Instead I moved on to the next moth I didn't know.
Quite a big micro, the same size as the several Cydia splendana also present in the trap. Obsidentify told me it was definitely Cydia amplana. It meant nothing to me, but I assumed it was just one of the many common micros I hadn't come across previously.
Can you guess where this is going?
After emptying the trap I went indoors to check the books and on-line. I spent ages comparing photos of several very similar species before tentatively concluding that the N molliculana was most likely that species. The downside of my approach is that I don't know which feature is the critical one to look for. (With birds I always know what I need to consider). So my photograph didn't show the thorax particularly well, but on balance I think it's right. I also checked a spreadsheet I have from the micro-moth recorder which gives a numerical code which tells me whether a specimen might be needed. It wasn't...phew.
Turning to the Cydia amplana, the picture in the book didn't look as similar to my moth as I'd hoped. However, checking on line I couldn't find any other likely candidates, and a couple of images were bang on. The English name the book gives is Rusty Acorn Piercer. Doesn't sound rare does it. Lots of acorns in Britain.
When I came to check the Guidelines, its name wasn't there. Uh oh! New for Warwickshire? I had another look at the book. The text said scarce migrant, possibly breeding on the south coast.
People might want to see this moth.
I went to the cardboard box where I'd roosted the moths, but it had gone. So if you are reading this as an experienced local mother who would dearly have loved to add this moth to your county list, I'm very sorry for your miss.
One last thing. Obsidentify can also save you from overlooking stuff. Resting on the fence were a number of grass moths, one of which I decided was Common Grass-moth Agriphila tristella. But the pale streak along its length bothered me a little. So I pointed the phone at it, and discovered it was actually Agriphila selasella Pale-streaked Grass-moth only the second I have identified in the garden.
I wonder how many I have previously missed.
I should say that Obsidentify isn't necessarily the best AI tool available. It is a Western European organisation based in Netherlands. This means for example that the Rusty Acorn Piercer was described as fairly common. It's easy to forget that this means in Holland and not necessarily the UK.
