You like spiders?

Support us in Frankfurt/Main in the arachnological collection and in database maintenance

The research of the Section Arachnology contributes to the research area of Biodiversity, Systematics and Evolution.  

Support us in Frankfurt am Main in the Arachnology Section (spider research) by sorting, reorganizing, labeling and georeferencing datasets.

As basic requirements you should bring patience, stoa and basic computer and geography skills. Furthermore, you should of course not be afraid of spiders. Further training will take place on site.

Comment from a volunteer:

“…Sorting the documents according to established rules with proper support made it easier to get started.

More frequent reading of the documents deepened my perspective and a broader insight into this other world received my attention. The world of the pointed spider, a drumming spider in defense mode, the architects among spiders, spiders under water, poisonous and less poisonous species, rolling Namibian spiders and many more.

Meet exceptional people! My encyclopedists! A heartfelt thank you goes out to my supporters.

For any curious person who wants to understand and learn, a stay – like mine – is recommended.”
