eReca Butterflies (UK)

A wildlife biological recording app covering (most of) the butterflies in the UK. This app is designed to record species in their natural environment using OpenStreet map as a backdrop. Species are selected from a list and stored in the SQLite database for export to a PC via eMail or loaded directly to the eReca server and posted to the web after appropriate validation, and onward to the National Biodiversity Network.

This smartphone app uses offline map storage and it's possible to create your own offline maps using Mobile Atlas Creator. These maps can then be uploaded to the device for use. Also, all map tiles downloaded through normal day-to-day use are retained for offline access.
