This juvenile Greenfinch was with a family group. At this age do not look at all green, but the large pale bill is very obvious. Not also the light flammulation on the breast and belly.

I was surprised to find this resting Small Skipper butterfly (Thymelicus sylvestris) visible on such a gloomy morning.

This photo of a moth is a repeat from yesterday when I made a pig's-ear of its identification. I thought it was a Marbled Beauty but inexplicably wrote Marbled Green. Thanks to some expert help I now know it is my first Small Ranunculus (Hecatera dysodea). This moth declined rapidly in the very early 1900's and was thought to be extinct in the UK until 1997. Since then it has spread thinly but widely across the UK.

Another gloomy shot of an ichneumon wasp. Cannot match it with anything on the web.

Another male Long Hoverfly (Sphaerophoria scripta).

At last – a female Long Hoverfly (Sphaerophoria scripta)! Note the thinner yellow bands on a wider and shorter body.

A better(?) photo of a Potato Capsid bug (Closterotomus norwegicus).

This tiny insect is one of the 99 UK species of what are variously called owl-midges, moth-flies or drain-flies. None is readily identifiable.

Rather gloomy when I took the photo of this beetle – it is Lagria hirta.

A small pale orange fly. Might be Tricholauxania praeusta, though of course there are 'similar species'.

A rather different view of a Scorpion Fly (Panorpa sp.). I used to think that separation of the two UK species was possible from the wing-pattern but I now read that this is unreliable.
