Biology
A. jeanae induces inconspicuous, externally imperceptible galls in stems of Silphium perfoliatum (Fig. 4H) (Tooker et al. 2004; Nastasi and Deans 2021).

Distribution
Tooker et al. (2004) reported this species only from several prairie sites in Illinois (USA). Nastasi and Deans (2021) did not report additional localities. However, specimens we examined revealed records from three additional state records: Indiana, Iowa, and Wisconsin. A verifiable iNaturalist observation (https://www.inaturalist.org/observations/114414672) also records this species from Ohio; we have since examined adult gall wasps reared from the plant material from the same site, which confirmed their suspected identity (in litt.). Lastly, a specimen identified during this study (USNMENT 01822302; see complete specimen data in Suppl. material 1: table 1) confirms the occurrence of this species in Missouri (Columbia, Boone County) (see discussion). Known and potential distribution are summarized in Fig. 9.
