| scientific name Chlorochroa uhleri Stal habitat No information available. seasonality Adults have been collected from March to August. identification The dorsum of this species is generally pale green. C. uhleri has reflexed anterolateral margins of the pronotum. The pronotum, corium and scutellum exhibit numerous pale callosities, scutellum withwith three distinct calosites at base and a pale apex. Costal margin pale. Rostrum just surpassing hind coxae. C. uhleri is extremely similar in appearance to C. sayi and they have nearly identical male genitalia, historically the two have often been confused. However, C. uhleri has a membrane without purple flecks, the embolium is apically wider and the calosites on the scutellum are smaller. Furthermore, Buxton et al. 1983 showed that there are no records for C. sayi north of 46?N. Length 12-16 mm. life history No information available. conservation No information available. diet info This species can be a serious pest on wheat in some years, attacking developing grain. The damage initially attributed to C. sayi in western Canada was caused by C. uhleri (Buxton et al. 1983). In the United States this species is most common on Salsoa spp., Descurainia pinnata, Medicago sativa, Triticum aestivum, and Sisymbrium attissimum. In British Columbia has been taken on Balsamorhiza sagittata (Scudder and Thomas 1987). range This species is confined to the western half of the continent having been reported from the Pacific coast to Colorado, Nebraska, New Mexico, North Dakota and South Dakota and to Saskatchewan in Canada (Buxton et al. 1983). The extensive records of C. uhleri in eastern Canada refer to C. persimilis (an eastern species) (Scudder and Thomas 1987). Similarly, many of the British Columbia records refer to other species (Scudder and Thomas 1987). quick link http://www.entomology.ualberta.ca/searching_species_details.php?s=4755
