About this app
This comprehensive field guide covers all 61 regularly occurring British & Irish butterfly species. Each species entry is illustrated with superb artwork by Richard Lewington and depicts each stage of the life-cycle: adults (including variation between broods, sexes and forms), larvae/caterpillars, pupae and eggs. Photographs, charts showing flight times, detailed maps and specially commissioned text ensure this app will provide every butterfly watcher with all the information they could need. FEATURES: • annotated illustrations by Richard Lewington • comprehensive collection of still photographs including larval and pupal stages • detailed distribution maps • flight time charts (phenograms) showing which life stages to expect when • compare any image side-by-side in Compare mode • detailed reference text for every species on all aspects of its biology • sort alphabetically or by family • seamlessly move between species by swiping up or down on illustrations • jump out of the app with a single tap to view coverage of the species in Chris Manley's ‘Moths of Britain & Ireland’ app, if installed
