Success length for COI sequencing by specimen collection date (given in percentage values at each bar) for the 8,549 USNM specimens selected in 2018 and 2019. The green bar represents the percentage of specimens collected per decade with recovered sequences (> 300 bp) and orange represents specimens with failed sequences (0 - 299 bp) or flagged sequences.
