SeasonalitySpecimens have been collected from May to July.
Identification6.5- 7.0 mm. In Alberta, species of the genus Phimodera are generally slightly smaller and darker in colour than other scutellerids (excepting Fokkeria producta). P. binotata and P. torpida are characterised by a broad X-shaped pattern on the pronotum and paired pale stripes on the leading edge of the scutellum, just below the pronotal angle. While both species of Phimodera in Alberta are quite similar, P. torpida is only known in the province from one record and is probably less likely to be encountered.
