The Gall Midges (Diptera: Cecidomyiidae) of Hickories (Juglandaceae: Carya)

Gliaspilota glutinosa (Osten Sacken), new combination

Cecidomyia glutinosa Osten Sacken 1862: 193; Felt 1909: 115 {Caryomyia); Gagne 1989: 211 {Cecidomyia); Gag- ne 2004: 277, as unplaced species of Cecidomyiinae.

Hosts: Carya cordiformis, glabra, tomentosa, ovata

Gall (Figs. 175-177): Occasional on both Eucarya and Apocarya sections, single or several on the underside of a leaflet; a discolored, mustard-yellow, irrregularly ovate spot on the leaf lamina, 5-8 mm in diameter; presence apparent from top of leaf only by discoloration, but on bottom of leaf covered with a colorless mucilaginous substance.

Biological notes. — Usually one, up to three free-living larvae can be seen in the liquid on each spot on the lower surface of leaflets. After full-grown larvae drop to the ground, the tissue under the mucilage dries, and the leaf is left with an ir- regular, brown spot. In northeastern United States fresh galls can be found as early as mid-April. Larvae have all dropped to the soil by mid-June. In Florida I found fresh galls in September, so it is possible this species has more than one generation per year there.
