The larva is largely immobile and is fed and cared for by workers. Food is given to the larvae by [[trophallaxis]], a process in which an ant [[Regurgitation (digestion)|regurgitates]] liquid food held in its [[Crop (anatomy)|crop]]. This is also how adults share food, stored in the "social stomach". Larvae, especially in the later stages, may also be provided solid food, such as [[trophic egg]]s, pieces of prey, and seeds brought by workers.

The larvae grow through a series of four or five [[moult]]s and enter the pupal stage. The pupa has the appendages free and not fused to the body as in a [[Chrysalis|butterfly pupa]].<ref>{{cite book|author=Gillott, Cedric |year=1995|title=Entomology|publisher=Springer|isbn=978-0-306-44967-3|page=325}}</ref> The differentiation into queens and workers (which are both female), and different [[caste (biology)|castes]] of workers, is influenced in some species by the nutrition the larvae obtain. Genetic influences and the [[polyphenism|control of gene expression]] by the developmental environment are complex and the determination of caste continues to be a subject of research.<ref>{{cite journal|title=The causes and consequences of genetic caste determination in ants (Hymenoptera: Formicidae) |first1=Kirk E. |last1=Anderson |first2=Timothy A. |last2=Linksvayer |first3=Chris R. |last3=Smith | name-list-format = vanc |journal=Myrmecol.

Some species, such as [[army ant]]s, have wingless queens. Larvae and pupae need to be kept at fairly constant temperatures to ensure proper development, and so often are moved around among the various brood chambers within the colony.<ref>Hölldobler & Wilson (1990), pp. 351, 372</ref>

A wide range of reproductive strategies have been noted in ant species. Females of many species are known to be capable of reproducing asexually through [[thelytoky|thelytokous parthenogenesis]].<ref>{{cite journal|last=Heinze|first=Jurgen |last2=Tsuji|first2=Kazuki| name-list-format = vanc |year=1995|title=Ant reproductive strategies|journal=Res.

Contrary to popular belief, some ant nests have multiple queens, while others may exist without queens. Workers with the ability to reproduce are called "[[gamergate]]s" and colonies that lack queens are then called gamergate colonies; colonies with queens are said to be queen-right.<ref>{{cite journal | vauthors = Peeters C, Hölldobler B | title = Reproductive cooperation between queens and their mated workers: the complex life history of an ant with a valuable nest | journal = Proceedings of the National Academy of Sciences of the United States of America | volume = 92 | issue = 24 | pages = 10977–9 | date = November 1995 | pmid = 11607589 | pmc = 40553 | doi = 10.1073/pnas.92.24.10977 | bibcode = 1995PNAS...9210977P }}</ref>
