Lonicerae russoi

Chiosperma turgidum

Lonicerae russoi is responsible for a green, leafy rosette bud gall (Fig. 1, this paper, and plate 238 of Russo (2007)) on Lonicera hispidula. Russo (2007) reported that galls usually appear several together at the tips of shoots, but may occur singly also. Individual galls may be 10 mm high by 8 in diameter and the clusters 30 mm in diameter. Individual leaves or bracts covering the galls are about 3 mm wide. White hairs protrude from edges of the bracts and more densely from the center of each gall. The individual larval chambers are 4 mm long by 2 mm in diameter.

This species is responsible for an elongate, swollen bud gall (Fig. 3) on Symphorocarpos albus.
Buds are enlarged, about 5 mm wide by 8–10 mm long, and do not open.

Three new genera and three new species of Nearctic Lasiopteridi (Diptera: Cecidomyiidae: Cecidomyiinae) from Asteraceae and Caprifoliaceae, and the tribe Rhopalomyiini subsumed under Oligotrophini
