Bibionid Flies

One of two small male Bibionid flies, probably Bibio johannis (Diptera: Bibionidae),  that I came across on nettles on the dam at the lower end of the large lake.  Male Bibio lanigerus are similar but their bodies are covered with white hairs instead of black (see here). 

Here is the second one, which jumped onto my hand:

Soldier Fly with Prey

A soldier fly, probably a Dioctria rufipes (Diptera: Asilidae), with its prey.  The characteristic of this species is the combination of reddish front and middle legs with black hind legs.  This particular specimen has lost half of one of its middle legs.

White Slime Mould

From yesterday afternoon: a young, plasmodial form of the slime mould Enteridium lycoperdon.  A little further down the tree trunk were these examples of the later silver-crust stage of the same species:

Bee Flies

From a week ago: a bee fly, Bombylius major (Diptera: Bombyliidae) feeding from blossom.  Photo taken in the Wilderness, Reading University grounds, Reading, UK, on 2011-03-24.

From last April, here is a side view of a female, showing the long proboscis that is characteristic of genus Bombylius:

Robber Flies

From last year: a male robber fly, probably of species Dioctria hyalipennis (Diptera: Asilidae).  According to Stubbs and Drake (British Soldierflies and their Allies, 2001) this fly would be classed as Dioctria baumhaueri but that is now regarded as just a colour-variant of D. hyalipennis (see here for more details).

Here are a couple of photos of a dead one I came across a few days later:
