Yes, I know. Siphonas are close to impossible to ID from photos. But I keep hoping. This one resembles S. boreata in the gallery. Is it, or do I have another Siphona sp. on my hands?

Size: ~5mm
Date: 23 August 2009
Location: On Tansy, Tanacetum vulgare, farmlan, meadow near water (Kulla Gunnarstorp, Sweden)

Thanks!

I think I see marginals on T1+2, which would suggest it isn't S.boreata, as described in Andersen (1996)

All Siphona resemble all Siphona in the gallery, so that does not mean anything.

Chris pointed out that it is likely to be geniculata or cristata.
