Occurrence of B. pensylvanicus (larger black circles) and B. sonorus (smaller yellow circles) within Texas based on iNaturalist observations (A) locations sampled for this study (B) showing locations with B. pensylvanicus (black circles), B. sonorus (yellow circles), and both species (half black and half yellow circles) as identified by ddRADseq. White dots over colored circles are locations from which mtDNA sequences were also obtained. Orange line indicates the apparent eastern- and southern-most extent of B. sonorus (based on iNaturalist data) for ease of comparison between the two figures.
