Brood VII

The Onondaga Brood

Brood VII, the Onondaga Brood, contains only M. septendecim and is currently found only on the Onondaga Nation in upstate New York. Populations near Rochester seem well documented, and several collections exist from Great Gully populations. However, the brood appears to be contracting. For more information see Cooley et al. (2004); Pechumen (1968); Pechumen (1984).

Brood VII
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.
