Brood IX

Brood IX populations in North Carolina are more or less restricted to upland sites, but some isolated populations are found in lower elevation areas adjacent to the Blue Ridge.

Brood IX
Brown symbols are verified records in the Database in February 2017. Gold are from Simon (1988). Blue symbols are from Marlatt (1923). Smaller symbols are records with a lower degree of certainty, and question marks or open symbols (on top of other symbols or alone) represent records that are considered spurious. Symbols are in layered in the order Database, Simon, Marlatt, and symbols in the upper layers may obscure symbols in lower layers.
