This is the aptly named Dwarf Snail Punctum pygmaeum. I'm still amazed I managed to spot it at 1.2 mm! I've included my lucky piece of laminated graph paper for scale. You can tell it's not an immature snail of a larger species because the number of whorls (>3.5) show it's an adult. I could just discern these whorls with the naked eye which made me have a closer look.
I added nine species to my list including a couple of great looking harvestmen, Anelasmocephalus cambridgei and Mitostoma chrysomelas (as well as lots of the odd looking Homalenotus quadridentatus I found there two years ago) . I found a smart looking staph called Quedius picipes and this earwig which I thought looked different to the common one. Indeed, it is Lesne's Earwig Forficula lesnei. Finally, I've seen one other than the common one! It was the fact that the hind wings were not sticking out that led me to think it was different (although I didn't know this until I keyed it out).
I also saw the nationally scarce ground bug Drymus pumilio which is about half the size of the much commoner Drymus sylvaticus with which it was found. This is quite a scarce bug and is only the second time I have seen it.
Not scarce, but it's always nice to put a name to a face. This large caterpillar was bright and patterned enough for me to have a go at identifying it and I'm quite confident it's the larvae of the Brown Rustic moth.
Here is the kind of clump of moss that was coming up with so many species. It has the English name Big Shaggy-moss Rhytidiadelphus triquetrus.
So I added nine new species putting me on 4753. That's 35 new species so far this year. Slightly under my required target to get 10,000 by the time I'm 40 but it is January and the day is but young!
