Diastrophus kincaidii
thimbleberry gallmaker wasp, thimbleberry gall wasp
Diastrophus kincaidii is a cynipid wasp that induces integral stem galls on thimbleberry plants (Rubus parviflorus). The galls form the basis of a complex derivative ecosystem, supporting a weevil and at least nine species of parasitic wasps. Females are flightless and exhibit communal oviposition behavior, with multiple females often ovipositing at the same site. Gall shape and size influence parasitism rates, with large, round, multilocular galls showing lower parasite frequency than small or narrow galls.

Diplolepis rosaefolii
Diplolepis rosaefolii is a gall wasp in the family Cynipidae that induces distinctive lenticular (lens-shaped) galls on the leaves of rose plants across Canada. The species exhibits an alternation of generations life cycle typical of cynipid wasps, with a bisexual spring generation producing the visible galls and an agamic (asexual) winter generation of wingless females. In Ontario and Quebec, it is primarily associated with native Rosa acicularis, though populations have been documented on the cultivated hybrid rugosa shrub rose 'Thérèse Bugnet'. The galls support a diverse component community including multiple parasitoid wasp species and inquilines.

Disholcaspis eldoradensis
Honeydew Gall Wasp
Disholcaspis eldoradensis is a gall wasp in the family Cynipidae that induces distinctive galls on valley oak (Quercus lobata). The species is notable for producing sucrose-secreting galls that attract ant mutualists, particularly invasive Argentine ants, which defend the galls against parasitoids. This mutualism creates a complex trophic community involving multiple ant species, parasitoids, and other associated insects. The species exhibits variable ecological outcomes depending on local conditions, with ant defense benefits varying across years and gall characteristics influencing parasitism rates.

Tetropium parvulum
Northern Spruce Borer
Tetropium parvulum, the northern spruce borer, is a small cerambycid beetle specialized on spruce hosts. It was elevated from synonymy with T. cinnamopterum based on distinct morphological differences in larvae and adults, and exhibits strict host specificity to Picea compared to the conifer generalist T. cinnamopterum. The species has a one-year life cycle and is an economically important borer of white and Engelmann spruce logs in western Canada.
