Western Subterranean Termites

The alates of subterranean termites.

The winged (or "alate") caste, also referred to as the reproductive caste, are generally the only termites with well-developed eyes, although workers of some harvesting species do have well-developed compound eyes, and, in other species, soldiers with eyes occasionally appear. Termites on the path to becoming alates going through incomplete metamorphosis form a subcaste in certain species of termites, functioning as workers "pseudergates" and also as potential supplementary reproductives. Supplementaries have the ability to replace a dead primary reproductive and, at least in some species, several are recruited once a primary queen is lost. (From Wikipedia)
