Query Scoparia basistrigalis

[CliveJ]

Could this, from my allotment trap on 26/06/19) be Scoparia basistrigalis?

? Scoparia basistrigalis?

Also, from the same night, one i'm more sure is Tachystola acroxantha.

Tachystola acroxantha

Hi Clive

Tachystola acroxantha is correct.

Is anyone on the forum familiar with Scoparia basistrigalis ? Recently published distribution maps show it as being present in the county but I have yet to find a genuine example. There are none in Manchester Museum and the few I have dissected have all turned out to be Scoparia ambigualis.

Thanks Steve

If there are no opinions to the contrary I'd happily settle for S ambigualis. This moth did not appear particularly large for one of this group. i was led towards basistrigalis by the illustrations in Sterling & Parsons which show plain fringes for ambigualis and chequered for basistrigalis, but images online show lots of moths identified as ambigualis with fringes every bit as chequered as my moth. I found this online, but it doesn't help me greatly! http://bmg.b-i-s.org/upload/library/The_Scopariinae.pdf
