Book excerpt: Excerpt from Proceedings of the Entomological Society of Washington, Vol. 104: July, 2002 The present study was based in large part on dissections of samples of galls of the gall midge, Rhopalomyia florella Gagné (diptera: Cecidomyiidae), on Artemisia tri dentata Nuttall prob. Ssp. Parishii (a. Gray) H. M. Hall and Clements (asteraceae) col lected mainly km north of the hamlet of Mile High and just south of the hamlet of Largo Vista; 1580-m elevation; Township 4n, Range 9w, Section 4; Angeles National Forest, Los Angeles Co., during 1996 and 1997. Excised R. Florella galls, containing eggs and early-instar larvae of 0. Palpalis, and later, overwintered galls containing third instars and puparia of O. Palpalis were sampled mid-monthly from gall-bearing plants during 1996 and 1997. Samples were transported in cold-chests in an air-condi tioned vehicle to the laboratory and stored under refrigeration for subsequent dissec tion, photography, description, and mea surement. Eight eggs, 18 first seven sec ond and 19 third - instar larvae and nine puparia dissected from galls were preserved in 70% etoh for scanning electron micros copy (sem). Additional prepuparia and pu paria in excised, opened galls were placed in separate, glass shell vials stoppered with absorbant cotton and held in humidity chambers at room temperature for adult and parasitoid emergence. Specimens for sem were hydrated to distilled water in a de creasing series of acidulated etoh. They were osmicated for 24 h, dehydrated through an increasing series of acidulated etoh and two, l-h immersions in hexa methyldisilazane (hmds), mounted on stubs, sputter-coated with a gold-palladium alloy, and studied and photographed with a Philips XL - 30 scanning electron micro scope in the Central Facility for Advanced Microscopy and Microanalysis, University of California, Riverside.
