Caryomyia stellata
Gagne Description 3
Occasional, on Eucarya hickories; single or clustered, on lower leaf surface between veins; 5.0-9.0 mm in height, elongate-conical, base flared laterally, the flat- tened edge often stellate, sometimes merely irregularly lobed, cone usually greatly attenuate and slightly curved to apex, furrowed; surface smooth, bare, green turning purple; base with shallow, circular, central excavation, leaf with no exfoliation surrounding connection; larval chamber ovoid, located at base of gall, surrounded by yellowish pellicle different in texture from soft, viscous, usually purple surrounding tissue that collapses with age, a bundle of fibers traversing between larval chamber and gall apex. Galls from Florida, Georgia, and Maryland are only tentatively placed with this species. They are the only ones found east of the Appalachians and are only shallowly lobed at the base and the lobes are rounded. West of the Appalachians the galls are more common, the bases more stellate, and the cones much longer (Fig. 143). Galls of this species have the same basic shape as those of C. sanguinolenta except for a much higher crown and flared sides.
