The genus belongs to the group of true weavers (subfamily Ploceinae), and is most related to Foudia, a genus of six or seven species that occur on the islands of the western Indian Ocean. This clade is sister to the Asian species of the genus Ploceus.
The following tree represents current insight of the relationships between the species of Quelea, and their closest relatives.

Q. quelea is a major pest to small-grain cereal crops in much of sub-Saharan Africa; the kernels of corn are too big for it. Q. erythrops may cause substantial damage to rice. Q. cardinalis is not known to raid crops.
