Identify butterflies and common day-flying moths of Western Europe, including all British butterflies. The app covers an area from Ireland in the west, eastwards to Austria, south to Sicily and north to Finland and Sweden. Select just the species from one country, or browse through all the species.

The specially written information about each species includes a variety of photos showing males, females, upper and undersides and any variations, plus a distribution map and notes on appearance, habitat, favourite nectar source, distribution and rarity status. More species will be added at regular intervals.

As with other Spiny nature guides, extensive record keeping features are included, with iCloud syncing to keep your data safe. Note the location, time and date of the sighting, make notes, view your records on a map or as a list, and download as an Excel file.

You can even add your own photos to the app to compliment the images provided and to really make the app your own!

The app also includes a photo-based Butterfly Finder to help identify mystery butterflies using a combination of filters including details of appearance, location, altitude and date.
