0 an insect in the stage of development after it has been a larva and before it becomes an adult, during which it is contained in and protected by a hard covering and does not move:
In ground beetles, a complete life cycle from egg to larva to pupa to adult takes one year.
Fireflies survive in soil through the winter, turn into pupae in spring, then emerge in summer as winged adults.
She monitors the butterflies as they emerge from their pupae.
The picture shows a pupa case, where caterpillars transform themselves into moths.
Each counting area was 1 cm2 and all whitefly eggs and pupae within the area were counted.
Critical stages of mortality were egg and larva during the rainy season and larva and pupae during the dry season.
The ability to store male pupae for some time before emergence and irradiation provides a useful degree of flexibility in operational programmes.
The pupae collected from each of the cultures were placed in clean plastic containers and adults were provided with 20% honey-water as food upon emergence.
