The knowledge-base for this visualisation is adapted from a spreadsheet created by Nigel Cane-Honeysett which, it turn, is created from tables originally published in The Spiders of Great Britain and Ireland (three volume set by Michael Roberts). By carefully observing just a few leg characters of a money spider (family Linyphiidae) under a microscope, you can narrow down the field of candidate taxa in this large family of 280+ species. Look at the taxon details (click on a taxon name) to see extra notes and page references for Roberts and Locket and Millidge. Note that the taxonomy reflects that used by in Roberts - not the latest UK taxonomy
