Field expeditions are the foundation of biodiversity research at AracnoLab. Since 1996, our team has conducted systematic collecting expeditions across Brazil and internationally, documenting arachnid fauna in diverse ecosystems from Atlantic Forest reserves to Amazonian rainforests. These expeditions have resulted in hundreds of new species discoveries and contributed significantly to our understanding of Neotropical arachnid diversity.
