PKS 1510-089 is a Flat Spectrum Radio Quasar at z = 0.361 with radiative output dominated by the γ-ray component and high variability over the whole electromagnetic spectrum. In particular, in the last two years very high γ-ray activity was detected by AGILE with flaring episodes in August 2007 and March 2008 and an extraordinary activity during March 2009. Observations in optical/UV seems to indicate the presence of Seyfert-like features in the broad band spectrum of PKS 1510-089, such as the little and big blue bumps. Moreover, X-ray observations in March 2008 show a harder-when-brighter behaviour quite rare in FSRQs. We present the multiwavelength data of PKS 1510-089 collected by GASP-WEBT, REM, Swift and AGILE during these γ-ray flares.
