  • These are current keys – classified according to level of expertise required Try the minibeast key as a simple example
  • Pick characters in any order – ignore any that are difficult Select closest match to your specimen Species listed in order of most likely – when id looks close, ticks will appear Repeat for more characters until you are satisfied Click on any species for a full description to check likely ids Characters used so far Change your mind – select character used and either change or delete
  • Set your location may help because gives greater weight to species found in local area. Only available for keys that go to species level (so not minibeasts). Other keys give more weight to common species regardless of location. May not be useful if distribution data is not good.
  • Check a description at any time – photos and text Description from key shows agreements in bold, disagreements in italic Distribution maps available from NBN
  • Choose two species to compare – look for differences between them to help discriminate Again, current characters which agree with species are bold, disagreements are italic
  • If you have a hunch you know what the species is, choose ‘diagnostic characters’ tab This shows most useful characters to check for that species If you click the button indicated, then this order of characters will be used on main identification tab
  • Mobile versions can be used on any phone with web browser Supports both larger screen with touch interface (eg iPhone) – quite easy to use And small screen and cursors (ie any phone with web access) – quite fiddly! Any comments welcomed
  • Possible to develop new keys – but currently only by arrangement! Hope to make this fully public in future but depends on obtaining additional funding
  • Preparing a key means filling in an Excel spreadsheet – this is the very simplest. Just upload the spreadsheet and the working key is generated automatically. It gets more complicated as you add more features!
