Common NameStriped Flea Beetle
SeasonalityAdults are active from April to October on the Canadian Prairies.
IdentificationAdults are 2-2.5mm, dorsally flat, elongate oval, black and have enlarged hind femurs. Each elytron has a distinctive pale yellow stripe that is wavy along its outside margin and curves towards the middle near the ends of the elytra. The 5th antennal segments of males are enlarged (Balsbaugh and Hays 1972). Unlike P. robusta, the yellow stripes do not reach the posterior elytral margins (Burgess 1977).
