This collection contains pinned Carabid adults from pitfall trapping (NEON sample class: bet_IDandpinning_in.individualID). Ground beetles are sampled using pitfall traps (16 oz deli containers filled with 150 or 250 mL of propylene glycol). Up to four traps are deployed in each of 10 plots at all terrestrial NEON sites (up to 40 traps per site), with traps arrayed approximately 20 meters from the center of the plot in each of the four cardinal directions. In 2018, NEON stopped sampling the 'North' trap site; only 30 traps were deployed per site per bout after that point. Sampling occurs biweekly throughout the growing season (when temperatures are above 4 degrees C). Following trap collection, all beetles from the family Carabidae are sorted by NEON technicians and identified to species or morphospecies. A subset of collected Carabidae are pointed or pinned, while other specimens (non-pinned/non-pointed carabids, invertebrate bycatch, and vertebrate bycatch) are stored in 95% ethanol for archiving, and may be pooled into a single archive vial per plot. Regardless of storage method, all collections data are reported at a per trap resolution. A subset of pinned ground beetles (up to 467 per site per year) are sent to an expert taxonomist for secondary identification. When multiple taxonomic determinations are available, expert taxonomy is used as the current determination. All other determination information is populated into the identification history for each specimen. See related links below for protocols and NEON related data products.
