Imaging To Follow

73.012  BF243   Burnished Brass Diachrysia chrysitis  

IMG_1197

The form tutti has the two vertical brassy bands on the forewing joined forming an “H-shape However the valid separate species named Diachrysia stenochrysis also has the two vertical brassy bands on the forewing joined “H-shape”. It is thought that the "H" needs to be at least 3 millimetres wide for it to be considered stenochrysis

I have summarised and simplified  the Form terminology  

http://www.sussexmothdiary.co.uk/macsheets/73.012.htm

Cryptic BB Diachrysia stenochrysis A good visual here on the species split images summarised

http://grampybustard.blogspot.co.uk/2010/07/burnished-brass-split.html

Summary top Image joint = Cryptic
Middle Image Banded Intermediate need gen det or dna
Bottom Image separate BB

On the BB Forms
    BB aurea has sepaarte vertical bars see http://www.sussexmothdiary.co.uk/macsheets/73.012.htm

juncta with the dark band complete, and tutti with the thin connect 3 mm

Moths with the 2 bands joined clearly and distinctly to create an "H"... have been referred to as f. juncta

Moths refererable to juncta are regarded BY SOME AUTHORS as a seperate species, called Diachrysia tutti

Examples of tutti in which the cross-bar of the H is at least 3 mm wide MAY BE REFERABLE to the Eastern Palearctic species stenochrysis

The intermediates I think need strictly speaking needs DNA to establish there validity

Marbled Minor (agregates  ) - 3 Sims

Marbled Minor Rufous Tawny

At a guess 1 & 2 possibly but NEEDS gen det especially their melanic forms, can only reliably be separated by dissection


Possibly 2339 Tawny Marbled Minor Oligia latruncula ABH 73.174

Great shots as usual. Appreciate the 'Y' tips Colin as have been struggling with several of these, especially those that look intermediate !

AndyC said...

Have a look into the types of Burnished BrASS ( THINK THERE ARE 3 ??) very interesting and great post ..

Colin D said...

Thanks Andy open to correction think its the conventional BB The other confusion species might be 73.011 [B&F: 2435] Scarce Burnished Brass (Diachrysia chryson) and 73.004 [B&F: 2433] Slender Burnished Brass (Thysanoplusia orichalcea) easily overlooked on afiner note

As you say or might have spotted or should I say H banded the forms of this are quite interesting and often overlooked added some notes under the entry above The form tutti has the two vertical brassy bands on the forewing joined forming an “H-shape which also occur at Cromwell. However the valid separate species named Diachrysia stenochrysis also has the two vertical brassy bands on the forewing joined “H-shape”. It is thought that the "H" needs to be at least3 millimetres wide for it to be considered stenochrysis. Rulers out everyone .HTH

if you put Burnished BRASS into the search at the top there are some older posts from 2010 and 2011 showing all 3 are seen in this area....cheers
