After mating, the female digs a shallow hole and deposits a single egg, which closely resembles a grain of white rice.

[7] Adaptations to arid climates and desert environments allow Pimelia to survive and reproduce in the dunes, but the relative importance of abiotic and biotic factors in this respect is not clear.

[8] Environmental factors influencing these adaptations are extremes of temperature and humidity, excessive radiant energy, low and irregular rainfall, long periods of drought, strong winds, unstable sand substrates, and sparse, specialized vegetation.

[9] Several morphological adaptations allow Pimelia to survive in the desert, including the lipid layers of the epicuticle, fused sclerites, the subelytral cavity, and the texture of the body surface.

Burrowing is probably the most important behavior modification for heat regulation in Pimelia, because it permits access to a broad range of ambient temperatures.
