Still slowly crawling towards full-blown spring here – mostly cloudy & not that warm yet 🤷‍♂️

But still some things to see in the garden, starting with this pretty fly.

From the colouration, & arrangement of bristles on the thorax & around the eyes, my best guess is a female common European greenbottle (Lucilia sericata; 🇩🇪 Goldfliege / Grüne Goldfliege).

Harder to photo & ID is this much smaller metallic fly, perched on the edge of a tulip.

From the shape & sheen, it's likely in genus Psilopa (shore or brine flies in English; Uferfliege in 🇩🇪), & one plausible option for the species would be P. nitidula.

That said, we're quite some way from any sea or brine, so maybe it's something else entirely 😬

@markmccaughrean Brine flies are common by ponds, but this looks more like a lance fly.

@chemoelectric Could be – there's a wide spread of metallic colours in that family. iNaturalist was fairly sure it's Psilopa, & there are some of those that look a lot like this, but I agree, the lack of a nearby pond isn't helpful to that theory 🙂

@markmccaughrean Where I live, there is nowhere that a pond is not nearby. :)

@markmccaughrean I mean, it is mid-continent and there are herring gulls everywhere.

@chemoelectric Ha – I’m still adjusting to living back in the middle of this continent after fifteen years just five km from the North Sea. And being halfway up a steep valley is equally weird …
