Pinned mosquito vouchers from CO2 trapping (NEON sample class: mos_identification_in.individualIDList). Mosquito abundance and diversity are sampled at regular intervals by NEON field technicians at core and relocatable terrestrial sites. Following collection, samples are sent to a professional taxonomist where a subsample of each catch generated from each trap is identified to species and sex. Specimens in this collection are pinned or point-mounted. See TOS Protocol and Procedure: Mosquito Sampling and TOS Science Design for Mosquito Abundance, Diversity and Phenology. NEON datasets (https://data.neonscience.org/home) associated with this sample class include Mosquitoes Sampled from CO2 Traps, Mosquito-borne Pathogen Status, and Mosquito Sequences DNA Barcode.
