Brood XXI

The Floridian Brood

Brood XXI was last recorded in 1870, in the Apalachicola River Valley. Records along the Georgia/Alabama border are almost certainly spurious.

Brood XXI
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.
