Note

a few other unidentified flies

Bugs:
- 1 *Dock Bug Coreus marginatus

Beetles:
- 1 7 Spot Ladybird Coccinella 7-punctata

Spiders:
- 1 *Garden Spider Araneus diadematus [Garden Cross Spider]

Fungus:
- *presumed Field Mushroom Agaricus campestris
- *unidentified species #1, probably from the Parasola genus
- *unidentified species #2

No identification problems with Dock Bug Coreus marginatus.

A Garden Spider Araneus diadematus also known as the Garden Cross Spider though the cross marking on this specimen is none too obvious. Top side...

...and from underneath.

I was not able to see the stem or underside of this fungus without destroying it. It looks to me like a Field Mushroom Agaricus campestris.

These delicate toadstools are from the Parasola genus which is all one can say from a photo.

These fungi look to have been trampled and I cannot get any identity for what they might have been
