Sadly without success, Caprainea marginata is meant to live on Keston common near me, although despite about 5 hours total searching so far I have never found it.
This time I did get some mites and a psuedoscorpion (hopefully it has not just eaten a Caprainea marginata)
All of these are on newspaper, I found them by sieving leaf litter onto it.
