「種」是分類的基本單位。同種植物的個體起源於共同的祖先，有極其近似的形態特徵，且能進行自然交配，產生正常的後代，有相對穩定的形態特徵，又在不斷地發展演化。不同種的個體在形態上具有差異性，不同的遺傳特性，一般不能進行雜交；即使雜交，所產生的雜交種後代也多為「不稔」，或產生不能正常生育的後代。
將具有相近親緣關系的一些種集合為一屬，相近的屬又聚為科，以此類推，分別組合為目、綱、門和界。如果在各等級之間，因範圍過大，不完全包括5其特徵或系統關系，可根據需要在該等級下增設一個亞級，如亞門、亞綱、亞目、亞科、亞屬等。種下分類設亞種、變種和變型。
目前已知的食蟲植物有10科，21屬，共611種。然而，由於某些食蟲植物的食蟲性尚有爭議，或者是新發現的食蟲植物尚未定名，因此現在仍不能真正確定到底有多少種食蟲植物。下表收錄現在已知的食蟲植物學名，其中包含無法確定的種類：
