Agonum gracile (above photo)
Tachyporus spp. (I think I have at least two species but need to spend some more time on them)
Stenus spp. (I have at least another two species, I need more time though!)
Common Pygmy Woodlouse
Common Striped Woodlouse
Common Shiny Woodlouse
Common Pill Woodlouse
What this illustrates is the importance of over-wintering structure for invertebrates. I also realised quite quickly that a tussock on the high and dry in or next to a wetland can be rammed with invertebrates. My 403rd species, making 10% of the 4034 or so UK species, was Agonum gracile above.
Also this week I have got hold of the key to springtails. I have two large specimens to look at today and see how the key works...
