Hidden moths: Make papillots visible in a streamlined way

Packed moths

In the papillot project, non prepared moths, which have been stored in pouches for decades, are made accessible to science by photographing, digitizing and storing them in a well-organized manner.

Digitized
for research

Every natural history collection has them: boxes or drawers full of bags of insects from historical expeditions and collection trips in which an abundance of enthusiasm has been collected. What to do with this collection? Most of the time these bags will stay on the shelve in 'eternity', because there is no time and money to prepare  them and it takes a lot of space to store them afterwards.  At Naturalis, a team of more than 60 volunteers worked for nine years, and made over 300.000 butterflies available.

Important
contribution

Naturalis Biodiversity Center has hundreds of thousands of papillots in its collection. The butterflies are collected from 126 different countries. A large part of these come from J.M.A. Van Groenendael's collection. He and his wife founded an NGO for the advancement of entomology in the Netherlands, which made important financial contributions to this project. 

Collections
opened up

Butterfly by butterfly, the tens of volunteers were unpacked, photographed and provided with digital information. This way, researchers from all over the planet can work with the data. The information is made available through our own Bioportal, and will be available through GBIF shortly.

Digital
species ID

So, what happens if a volunteer finds an envelope without a proper species name for the butterfly? Naturalis has and knows the experts that can identify the species, but not every museum has this luxury. The papillotten project helps other museum not just by sharing our methods, but also by using our butterflies to train an AI for species identification. Find out more about it here:

Image recognition as a tool for museum collections

In the project Automatic image recognition as a tool for museum collections, Naturalis and several other Dutch museums are investigating the use of artificial intelligence for object registration in museums. In this pilot machine learning is used to train…
