Butterfly

A red admiral butterfly, Vanessa atalanta (Lepidoptera: Nymphalidae).

Photos taken in Chazey Wood, near Caversham, UK, on 2012-09-30.

Beetle

A small black beetle with distinctive antennae: probably the cobweb beetle, Ctesias serra (Coleoptera: Dermestidae).  The name 'cobweb' derives from the habit of the larvae of stealing dead insects from spider's webs (see here for details).

Platypezid Fly

A female Polyporivora ornata (Diptera: Platypezidae).  I found this fly in the woods near the north-east corner of the large lake.  This is about 700m from where I saw the same species last year (see here and here).

Muscid Fly

A female Hydrotaea diabolus (Diptera: Muscidae).  Identification confirmed by Stephane Lebrun at Diptera.info.  Presumably named diabolus because of its distinctive blackness.

Note the long backward-pointing hair on the hind tibia.  It is best shown in the following photo.
