i5K Comments for Eurosta solidaginis
Eurosta solidaginis overwinters in diapause as a freeze tolerant prepupa. Its abundance and easy collection mean that it has been a model for a variety of experiments on metabolic suppression, overwintering ecology and freeze tolerance for nearly a century. Currently, four main groups work on freeze tolerance in this species (Lee, Miami; Storey, Carleton; Sinclair, U Western Ontario; Denlinger, Ohio State) as well as several successful research programmes at smaller, undergraduate-focussed institutions. In addition, E. solidaginis is of interest form population genetics and host-race perspectives (several active research groups), and is commonly used in a variety of undergraduate projects throughout NE North America. E. solidaginis is biologically interesting for several reasons: 1) It has an intense diapause (metabolic suppression) over winter. 2) It is freeze tolerant, surviving internal ice formation, intracellular ice formation and very low temperatures (some survival at -80 degC). 3) it is highly desiccation-resistant. 4) as a gall-former, it has interesting interactions with its host plant to form galls. 5) there are several host races corresponding to different species/population of its host plant, Solidago.
