The value of public databases for our knowledge of national spider biodiversity compared to a long‐term scientific monitoring project

open access: yesInsect Conservation and Diversity, Volume 19, Issue 1, Page 228-239, January 2026.
Records in citizen science platforms in Sweden are biased towards visible, diurnal, urban species but provide a cost‐effective way to gather large datasets and engage the public. National scientific surveys like the Swedish Malaise Trap Project remain essential to detect rare and cryptic species without activity bias, though some spider families are ...
