These typically become prepupa in mid- or late summer, then go into diapause for autumn and winter, resuming development in spring or early summer. [6] In honeybees, a larva about to become a prepupa first orients its anterior end towards the cap of its cell. It spins a cocoon around itself and progresses to the prepupa stage.
In the early stages of its life cycle, Dieunomia triangulifera spends the winter underground as a prepupa in a state of diapause, allowing it to survive harsh conditions. [4] This prepupa can be distinguished from that of Nomia melanderi by sharper dorsal prominences on the thorax, [4] and is butter-yellow with bands of orange between segments. [4]
Lifestages of a holometabolous insect ().Egg is not shown. Third, fourth, and fifth images depict different ages of pupae. Holometabolism, also called complete metamorphosis, is a form of insect development which includes four life stages: egg, larva, pupa, and imago (or adult).
The larva feeds on the secretions of a "milk gland" in the uterus of its mother. The female gives birth to a fully mature white prepupa. She may produce larvae for as long as 10 months. A newborn prepupa immediately darkens, forms the puparium, and begins to pupate on the forest floor, or where the deer are bedded.
Winter is spent in the soil as a prepupa. Adults emerge in late spring and females lay eggs in elongating shoots. Larvae feed on needles for 3–4 weeks, generally in late June and early July. However, emergence can be delayed for some individuals larva can be present throughout the summer.
Larvae completing their development late in the year cause the aphids to crawl downwards and find concealed spots. Here the wasp larva forms a cocoon inside the hollowed-out body of the host, spends the winter as a diapausing larva called a prepupa, and pupates in the spring to continue its life cycle. [4]
