Data of the Insect Biome Atlas: a metabarcoding survey of the terrestrial arthropods of Sweden and Madagascar
We present the raw sequencing data from the Insect Biome Atlas project (IBA). Over 12 months, weekly Malaise trap samples were collected at 203 locations in Sweden and at 50 locations in Madagascar. This was complemented with soil and litter samples from each site. The field samples comprise 4,749 Malaise trap, 192 soil and 192 litter samples from Sweden and 2,566 Malaise trap and 190 litter samples from Madagascar. Samples were processed using mild lysis or homogenization, followed by DNA metabarcoding of COI (418 bp). This data allows characterizing the terrestrial arthropod faunas of Sweden and Madagascar.
