 #### Data Collection and Processing
-[More Information Needed]
 <!-- This section describes the data collection and processing process such as data selection criteria, filtering and normalization methods, re-sizing of images, tools and libraries used, etc. 
 This is what _you_ did to it following collection from the original source; it will be overall processing if you collected the data initially.

+Beetles were collected in 2018 by NEON field technicians. In sum, Ground beetles are sampled using pitfall traps (16 oz deli containers filled with 150 or 250 mL of propylene glycol). Multiple traps are deployed in each of 10 plots at each terrestrial NEON site (from 2013-2017, 40 traps per site; 2018-present, 30 traps per site), with traps arrayed approximately 20 meters from the center of the plot in one of the four cardinal directions. Sampling occurs biweekly throughout the growing season (when temperatures are above 4 degrees C). The corresponding NEON data product for these data is entitled, "Ground beetles sampled from pitfall traps". More complete field and biorepository protocols can be found at this [link](https://data.neonscience.org/data-products/DP1.10022.001).

+This dataset specifically focuses on 2018 because at the time the images were taken in 2022, 2018 had the most complete spatial coverage of identified and fully processed beetle specimens (due to latency issues lingering from the pandemic and the time taken for experts to ID difficult species). Images were only taken of specimens stored in ethanol within vials as it was too difficult to ship the pinned specimens to the University of Florida where imaging took place.
