Bassettia pallida

Quercus virginiana, geminata
Stem galls, cells hidden under bark, some swelling
Described from a single female from GA April 15 without gall or host. Agreeing with type is a specimen from cells just under the bark of live oak in FL.

Described from a single female from GA April 15 without gall or host. Agreeing with type are specimens from cells just under the bark of small twigs of Q virginiana in FL, the adults emerging in Fed and Mar.

Bassettia pallida (Ashmead 1896)

Hosts: Quercus geminata, minima

Using gall wasps on oaks to test broad ecological concepts

Bassettia pallida Ashmead, 1896

Biology--Only the asexual generation is known which induces stem galls with cells hidden under the bark of Q geminata and virginiana. Adults emerge in April in GA and in March in FL.

Distribution--GA, FL

Review of the Nearctic gallwasp species of the genus Bassettia Ashmead, 1887, with description of new species (Hymenoptera: Cynipidae: Cynipini)

Bassettia pallida

internode clustered cryptic galls

Hosts: Quercus virginiana, geminata

Bassettia pallida Ashmead, 1896, sexual generation

Gall. Asexual galls (Fig. 112) are in twigs, larval cells develop as cryptic elliptical chambers 3.2 mm long by 1.2 mm in diameter under the bark of small twigs. 

Biology. Bassettia pallida, previously known only from asexual females, is now also known from its sexual generation. The asexual galls develop under the bark of twigs on Q. virginiana and Q. geminata. Galls mature in late September-October; adults emerge in November. Both sexual females and males were reared from galls within the same twig with enlarged and distorted buds on it, collected at the Archbold Biological Station (Florida) from Q. geminata in October. See Weinersmith et al. (2020) for the community ecology and natural enemy assemblage associated with galls. 

Distribution. USA: Florida, Georgia, Missouri (Burks 1979).
