Three d Scuti stars of Praesepe cluster (BT Cnc, KW 284 and EP Cnc) seem to be at the end of the hydrogen core burning in the subgiant phase. This is supported by the fitting of isochrones to the cluster and by the larger period of their pulsations compared to the other delta Scuti stars in the cluster. After the results obtained in a joint
