A survey of Pulsatilla grandis Wender revealed the presence of four aphid species colonizing Greater Pasque Flower in Hungary. Aphis pulsatillicola Holman, 1966 the monoecious Pulsatilla feeding aphid species is a new record for the Hungarian fauna. The development of Cavariella theobaldi Gilette Bragg, 1918 on the isolated silky seed head proves that the host alternating aphid species (primary hosts are Salix species and summer hosts are Umbelliferae plants) was able to develop from nymph to alatae on P. grandis. Winged forms develop in response to unsatisfactory quality of a host plant, while on suitable host apterae are produced. The polyphagous Aphis fabae Scopoli 1763 and Aphis gossypii Glover 1877 were able to overwinter and the progenies of fundatrices developed into wingless apterae on P. grandis.
