Both are small (approximately 10–12 mm), -mimicking with spotted wings that appear short relative to body length. Specific morphological differences between the two North American species are not detailed in available sources.
Distribution
Recorded from Florida and Texas, United States. This restricted range contrasts sharply with the widespread distribution of the congeneric A. canaliculata.
Diet
As a in the Ampulex, it hunts as prey. The specific prey for A. ferruginea have not been documented, though related species target wood cockroaches in the genus Parcoblatta.
Host Associations
- Cockroaches (Blattodea) - Specific unconfirmed for A. ferruginea; congeneric A. canaliculata targets Parcoblatta wood cockroaches
