Oh, I have just found this in Other Obs., after asking you to enlarge on the Mites.
Can you still do that? Make a post on the mites perhaps. They'll be new to most of us (unless I'm the only one!). This slug appears many times but so few agreements!
Where ARE the interested naturalists in this community?
Riccardoella limacum larger than that I cannot get without additional equipment.
The length of the mite is 0.4 mm so it is a subject for microscopy.
