It may be winter but there are still leaf mines to check for, if you live in a location where the Cow parsley (Anthriscus sylvestris) is already springing up – here in coastal south Wales, I’ve even spotted a few flowers, though the official flowering period is April to June.

The leaf miner is a fly, Phytomyza chaerophylli, whose larvae munch their way through the leaves of several umbellifer species and can usually be seen from early spring right through to the end of summer, sometimes even earlier and later if the temperatures are mild enough. You can read more about these leaf mines and see more images on the UK Fly Mines website.

I was handing out the cigars last Monday!
Now, you might well think me more than a little mad to be excited about the birth of a fly but this was the first time I had tried rearing one … and it was actually successful, which bodes well for the fact that I’m intending to take part in a fly-rearing investigation this summer (more on that closer to the time).

The fly is Phytomyza ranunculi, a creature whose larvae often make their home in the leaves of Lesser celandine (Ficaria verna). I blogged about this leafminer, its larvae and the pupa here, and it is that pupa which finally hatched earlier this week. I had been told it would take about 3 weeks to hatch but it was, in fact, longer than that – it was 6 February when I found the pupa and 12 March when it hatched, so 34 days in total.

Now, here I must admit to a rookie error. As it was well over the 3 weeks, I had almost given up on its hatching so, on Monday night, when I had a sudden notion to open the container, I didn’t look inside first. The fly popped straight out, perched on the edge for a very brief time – and I managed to get just one photo, and then it flew off. I’ve searched for it in my flat, and it did a quick fly by when I was washing the dishes yesterday, but I haven’t been able to find it, neither to take more photos nor to let it outside.
