Explore the diverse flora and fauna on the Downs from season to season through personal observations and photographs

Wednesday, 10 Dec 2025

Damper and damper, even the leaf litter in the woodland is now distinctly soggy.

I was only just onto the Downs today when I made my first discovery. Searching the underside of ivy leaves for anything of interest I found the pupa of a hoverfly (Syrphidae sp.) in plain sight on the upper surface of an ivy leaf.

In the woodland I thought I was taking a photo of an ant. The ‘ant’ turned out to be a wingless female ant-mimicking parasitic wasp (possibly of the genus Gelis) on a bramble leaf no doubt searching for the pupae of other insects in which to lay her eggs. The bramble leaf itself showed many larval leaf cut-outs, as well as old leaf mines probably caused by larvae of the Golden Dot moth (Stigmella aurella).

I literally just had to turn around to find a fly sitting on a large mushroom. Given the context this could be a fly of the Heleomyzidae family, possibly in the sub-family Suilliinae, as they can be found year-round and are usually associated with fungi and decaying matter as these are the larval food sources for these flies.

While photographing a Postia sp. fungus (possibly P. subcaesia, Blueing Bracket) on a fallen oak branch, I became aware of a woodlouse crawling in and out of my field of view. Subsequent processing of these images revealed it to be a Common Rough Woodlouse (Porcellio scaber). During processing I also discovered something I had missed in the field, tiny globular springtails were also present, probably Dicyrtomina saundersi, the same species that I first posted a week ago.

 

 

Many of the fallen and decaying branches in this area, mainly oak, birch or hawthorn, showed growth of Mycena sp. bonnet mushrooms. On a large pile of grass cuttings I found the now decaying caps of Wood Blewit (Collybia nuda) mushrooms. Digging away the grass around them revealed much more of these mushrooms.
