How a termite queen becomes an egg-laying powerhouse
A queen’s extraordinary output depends on a body built for reproduction. In many termite species, her abdomen enlarges after she mates, a change called physogastry. The expanded abdomen can hold the reproductive organs needed to produce eggs at high rates, while the queen herself becomes far less mobile than an ordinary termite.
That immobility is part of the arrangement, not a failure of the queen. Workers feed and groom her, keep the nest in suitable condition, and carry newly laid eggs to protected places. The queen can devote much of her capacity to producing the next generation because other members of the colony handle essential tasks around her.
A colony-wide production system
Egg production is costly: it requires food, energy, and a secure environment. A queen’s rate therefore depends not just on her anatomy but on the colony’s ability to supply and care for her. Species differ, and a peak rate is not a promise that the queen will maintain that pace continuously.
The result is a striking division of labor. One queen can generate a vast number of potential colony members, but those eggs become termites only if workers protect and raise them. The impressive number is a measure of the whole colony’s capacity—not just the queen’s.
