Testing preferences of female Eutreta diana to sagebrush plants that emit different odors 
Very rarely different galling species form galls so close on a stem that the galls grow together forming a gall chimera! The smooth purple top is from Eutreta diana. The hairy bottom is from Rhopalomyia medusirassa. 
Kayla working on her undergraduate honors thesis. She used the community of gall insects on sagebrush to tease apart the effects of host-plant size and age on herbivore community composition.
