Description	Rumex obtusifolius is the preferred host plant of Coreus marginatus. The survival of nymphal C. marginatus, its development on a diet of R. obtusifolius and the effects of herbivory on Rumex seed were investigated. Although the diet consisting solely of seed did not allow complete development, growth rates and survival of nymphs were proportionate to the quantity of provided seed. Nymphal feeding did not noticeably decrease seed mass but significantly decreased the proportion of germinating seed. In this way C. marginatus affects Rumex reproduction.
