Back home to cool, cloudy, & even drizzly weather. But not too bad for our garden arthropods.

First, a new one for me: a fig-tree skeletonizer moth (Choreutis nemorana; 🇩🇪 Feigen-Spreizflügelfalter), with its white underside & peculiarly folded wingtips.

A small moth seen side on feeding on some yellow flowers. The moth has a white head and thorax, with white forelegs. The eyes are grey with a black dot in the centre. The wings are seen from the underside, showing browns and whites, with two light brown spots near the rear edge. The wing tips are folded down partly. The same moth seen from above, looking down at its wings. These have a base colour of reddish-brown, with darker brown flecks and several crooked white transverse stripes. There is a larger dusting of white towards the rear, after which the wings are more red. Another view of the moth from the side and underside.

I saw this squat little fly last autumn & there were several feeding in the Canada goldenrod today.

The shape & markings lead to it being called the ladybird fly (Gymnosoma rotundatum). Despite being widespread in Germany, it lacks a common German name 🤷‍♂️

First picture is a female; the other three show a male.

A small fly seen from behind on some yellow flowers. The fly has red compound eyes and black antennae, followed by a mostly black thorax and scutellum, covered in yellow and orange pollen. The black thorax marks this as a female. The abdomen is quite globular and orange with fine hairs. There are two black spots down the centreline, plus a black patch at the top of the abdomen. There are black side patches near the end of the abdomen too. The legs are black, and the wings are slightly opaque grey turning orange at the case. It has large pale yellow halteres under the wing roots. The different fly of the same species seen from in front, likely a male. The red compound eyes are separated by cream patches and a red-brown central band. In this case, the thorax is seen to have a number of golden patches separated by thin black stripes, and there is a lighter stripe running down the scutellum. The same male fly seen side on. The same male fly seen from behind. Compare the white spot on the base of the scutellum with the all-black scutellum of the female in the first picture.
