ALL British butterflies PLUS the most common day-flying moths are here in this app. Day moths are as bright and colourful as any butterfly, so they are an essential addition - don’t miss out by buying an app without them! The information on 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.

NB This app features British butterflies and day moths. For butterflies found elsewhere in Europe as well as in Britain, please see our 'Butterfly ID Europe’ app.

As with other iSpiny 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.

Special features:
• All butterflies plus the most common day-flying moths of Britain and Ireland.
• A photo-based 'Butterfly Finder' based on appearance, habitat, location, date and more
• Carefully selected photos of males, females, upper and undersides.
• Labelled photos of key features
• A 'compare images'feature
• A 'History' feature to make it easy to go back to the last species you looked at
• A European distribution map for every species
• iCloud syncing to keep your data safe
• A back-up system so you can save your data
• Export your list of sightings to Excel
• You can add your own photos of the butterfly or its habitat
• Share your sightings with the built-in Facebook and Twitter links.

We have many years experience of developing biological software and this has enabled us to pack the app full of features while keeping it simple and easy to use. All the listed features are included in the app when you buy it - we don't have in-app purchase and we won't ask you to sign-up or register for anything.

Spiny apps are great


I have 5 Spiny apps and they all use the same interface which is very easy to use. Species can be identified and sightings logged with your own pictures. I especially like the ability to compare pictures of different species to help identify what you are looking at. It would be even better though, if it were possible to flick through all the pictures available and not just the ones selected. E.g. you may wish to compare the top of a butterfly or mushroom, the underneath and then the distribution.

Good app. BUT

A good app. with sufficient information. I was going to buy a book instead but went for the app. but never really thought about it: Butterflies like the sun, but phone screen cannot be seen. Oops.
