NABU - Zeit der Schmetterlinge is an Android application developed by naturgucker.de, available for free. It falls under the Education & Reference category and is a subcategory of books. The app provides detailed information and typical images of 50 butterfly and 25 plant species. These species portraits are supplemented by an identification aid in the form of an illustrated selection key. By recognizing distinct features, users can quickly select appropriate species in case they are unsure of what they are observing.

The app "Zeit der Schmetterlinge" is primarily a tool for nature observers, which enables them to identify common butterfly and plant species directly in the field or garden and professionally record their observations for later transfer to naturgucker.de or nabu-naturgucker.de. This process saves considerable time compared to making notes and capturing data retrospectively on a PC.

In addition to observations, users can also upload images of species or observation areas.
