The pupa is the stage between the larva and adult stages. The chrysalis generally refers to a butterfly pupa although the term may be misleading as there are some moths whose pupae resembles a chrysalis, e.g.: the plume winged moths of the family Pterophoridae and some geometrid moths. A cocoon is a silk case that the larvae of moths, and ...
The pupae of moths are usually brown and smooth whereas butterfly pupae are often colourful and their shape varies greatly. [21] In butterflies, the exposed pupa is often referred to as a chrysalis, derived from the Greek term "chrysalis": χρυσός (chrysós) for gold, referring to the golden colour of some pupae. [68]
The pupa – chrysalis – of the Mechanitis polymnia have a mirror-like metallic appearance. The polymnia chrysalises have a reflective coating which conceals the defenseless pupa by reflecting its surroundings to confuse predators. It is thought that predators see their own reflection in the chrysalis and then flee. [11]
Pteromalid wasps, specifically Pteromalus cassotis, parasitize monarch pupae. [188] These wasps lay their eggs in the pupae while the chrysalis is still soft. Up to 400 adults emerge from the chrysalis after 14–20 days, [188] killing the monarch. The bacterium Micrococcus flacidifex danai also infects larvae. Just before pupation, the larvae ...
A butterfly pupa, called a chrysalis, has a hard skin, usually with no cocoon. Once the pupa has completed its metamorphosis, a sexually mature adult emerges. Lepidopterans first appeared in fossil record in the Triassic-Jurassic boundary and have coevolved with flowering plants since the angiosperm boom in the Middle/Late Cretaceous. They show ...
Lifecycle: The lifecycle of Mylothris agathina follows the typical stages of a butterfly: egg, larva (caterpillar), pupa (chrysalis), and adult. The eggs are typically laid on host plants such as Hairy Mistletoe and African Sandalwood, where the caterpillars hatch and feed. The pupae resemble bird droppings. [2] After undergoing metamorphosis ...
The vast majority of butterflies have a four-stage life cycle: egg, larva (caterpillar), pupa (chrysalis) and imago (adult). In the genera Colias , Erebia , Euchloe , and Parnassius , a small number of species are known that reproduce semi-parthenogenetically ; when the female dies, a partially developed larva emerges from her abdomen.
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). Holometabolism is a synapomorphic trait of all insects in the superorder Holometabola. Immature stages of ...
