Tephritid on Knapweed

The attached images are from a site in Worcestershire, taken in mid August and have been sent out from the Wildlife Trust for ID.

As I'd attended the Dipterists Forum course on Picture wings at Preston Montfort I thought I'd have a go. 

I think it is Chaetorellia jaceae from the draft keys given out by David Clements. Is it?

Fanniidae?

Hi, can anyone help with this male specimen? I think it is a member of the Fanniidae, have attached photos to try to show hind tibia, it’s the Arista that is troubling me, long plumose seems to indicate Piezura miki in Fonseca? I have extended the genitalia but a micro pin is still in place while the specimen dries out!

Many thanks

Lucilia silvarum?

I don't normally attempt Lucilia but I am wondering if there is enough in this image to make it Lucilia silvarum? It's a single image taken on a boggy field (The Spearwort Fields) in Leicestershire, VC55, on 15.viii.2020.

thanks

Possible Callomyia elegans? ID advice greatly appreciated

I hope this is the correct place to post to request an ID - I am very new to Dipterists' Forum.  I found a very distinctive small black fly today - red eyes and halters, wing venation reminding me of Lauxiniidae - and have posted it for ID on one of the Facebook groups.  It has been suggested that it is most likely to be one of the Platypezidae, the fly's distinctive appearance seeming to suggest Callomyia elegans as a possibility.  Looking at the NBN atlas, however, there is only one record of that species here in the UK, the fly being on the Red List.  Is it possi
