A moth that came to my garden light trap.
No interactions present.
Hi Moremoth and David,
Does the selection of Mesapamea secalis agg. cover didyma and Remm's Rustic?
I would have thought that Mesapamea agg. would have more accurate but please refresh me on how Mesapamea secalis agg. works?
or two (if that is what you think there are), or twenty if they way taxonomy is going continues.
I wasnt remotely aware of the likelihood or possibility of Remms until today- if I had encountered it in the past I had completely forgotten.
No I dont think there are just 2 Mesapamea, I wouldnt be qualified to suggest anything like that. I wonder has there been any effort to detect remmi in Irish populations, they dont make reference to it yet- I could well have had remmi in my hand and not known it.
It covers all three species, IF Remm's exists! Two, if not. Whether Remm's exists or not, it will cover all specimens.
Just for consistencies sake I wanted to know what I should record them as. At the risk of sounding stubborn or maybe even just silly!- I would have thought Mesapamea agg. would have been preferable but thats just me trying to fully understand the whole business.
Not stirring I promise!!
that outside of the UK there are other species in the genus Mesapamea. Mesapamea agg. would therefore imply it could be one of them.
But I suspect it is more that there are not such rigorous rules for recording aggregates taxonomically and it is just a convention that this one is done as Mesapamea secalis agg
I normally follow a handy guide to recording difficult species put on line by a Berkshire group. It seems a sensible guide.
If you want to have a go at sorting these out (or other macros) there's a very good book produced by Butterfly Conservation and NMRS, Townsend, Clifton and Goodey, British and Irish moths: an illustrated guide to selected difficult species. It covers preparing genitalia and gives very good photos.
It sounds great Ardea, thanks for sharing. It could be the most helpful addition to field guides.
