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.

Caryomyia glutinosa

Carya sp.
Occurring on leaf, producing no gall
An irregular, yellowish, brown-margined elevation, diameter 3 mm, larva surrounded by a viscid secretion.

Yellowish leaf spot on underside of leaflet ... "Cecidomyia" glutinosa Osten Sacken

Spots are covered with a sticky substance. One larva lives on each spot and drops to the soil when full-grown. The spot then dries and turns brown. The yellowish-orange larvae are notable for their conspicuous, long, flattened dorsal lobes...Hosts: C. illinoensis, Carya spp....
