Websites
BMIG, the British Myriapod and Isopod Group is the membership organisation for study and recording of Millipedes, Centipedes, Woodlice & other Isopods. Its website has useful information about identification.
Google Lens: Go to google.com and there is a camera icon at the right of the search bar. Click on this, and you can drag and drop any image and it will do its best to identify it – so can be used for any flora and fauna, vertebrates and invertebrates etc. (as well as buildings, landscapes – anything, in fact.) Worth a look, but treat identifications with caution!
