The yellow sugarcane aphid Sipha flava (Forbes) is recorded for the first time in the Iberian Peninsula and also in the European continent, on the common thatching grass Hyparrhenia hirta (L.) Stapf in Oliver, in two localities of Catalonia (La Selva del Camp and Blanes, provinces of Tarragona and Girona, respectively; NE Spain). Data on its biology and distribution worldwide and notes on its pest behaviour are given. Sipha flava had been recorded previously from Azores Islands (in 1979), and recently from Morocco (in 2008)
