Brood XXI was last recorded in 1870, in the Apalachicola River Valley. Records along the Georgia/Alabama border are almost certainly spurious.
In the map below, red crosses are verified absence records in our database as of August 2023. Blue symbols are from Marlatt (1923); smaller symbols are records with a lower degree of certainty and question marks represent records that are considered spurious. Symbols are in layered in the order Database, Marlatt, and symbols in the upper layers may obscure symbols in lower layers. This map may not be reproduced without written permission.
