Life Cycle images of Polytela gloriosae (Lily Moth)


Polytela gloriosae Fabricius, 1775

Animalia > Arthropoda > Insecta > Lepidoptera  > Noctuidae > Glottulinae > Polytela > Polytela gloriosae


Life cycle observed on larval host plant Zephyranthes




Eggs are laid in batches like  most other moths and the number varies hugely. 




An early instar caterpillar. More reddish brown than black.

The colour turns darker as the caterpillar attains later stage instars.




A batch of caterpillars feeding on Rain Lily plant 




The later instar caterpillars usually feed on the plant from the top to bottom. They are observed eating the flower and the seedpods along with the leaves. 







Few grown caterpillars were seen feeding on orange pulp kept nearby. They continued to feed on them until the pulp became unavailable.

Description

Adult: Head and thorax blue-black; the basal joint of palpi and antennae orange; three orange specks on meetathorax; abdomen black, the terminal segments orange. Fora wing blue-black; an orange speck at base; the subbasal and antemedial waved lines filled in with orange, with an orange speck between them in cell, and two pink and black lunules towards inner margin; the orbicular a yellow ring-mark; the reniform yellow with the upper part centred with pink, the lower with fuscous; some orange specks on costa towards apex; the curved lunulate double postmedial line  filled in with yellow, and with a series of pink and black lunules beyond it; large orange blotches at apex and outer angle; cilia black and orange. Hind wing fuscous, with traces of an angled postmedial line; the cilia orange.

Larva: smooth; Purple-black, with dorsal, lateral, and sublateral series of white spots; purplish lateral blotches on thoracic and two terminal somites; head, legs, and a dorsal spot on 1st somite red.

Food-plant - Amaryllis.
Habitat. Throughout IndIa and Ceylon.

The adult was immediately released after it eclosed.

The observation is made during Sep - Oct 2017 from South India.

A caterpillar boring into a Kalanchoe leaf. 







Two caterpillars; one large and one small, eating the leaf from inside. 



Below video shown how a Red Pierrot caterpillar feeds on a Kalanchoe leaf from inside.







When the leafs are not enough, they even bore into the stem and feed on it. 



The colour sometimes changes based on the diet. 



After about two days of staying in one place, it becomes a pupa.



In two days, more spots begin to appear on the pupa.




In ten days, the colour changes slowly.




The pupa becomes almost entirely dark before eclosing.

The adults was immediately released after it eclosed.

The observation is made in July 2017 from South India.

Day 1: Caterpillar having its first meal. The egg shell.

Day 6 : The caterpillar feeding on palm leaf. Its host plant.
 
 
Day 10


Day 18


The caterpillars of skippers like Giant Red-Eye take much longer than butterflies of other families to pupate.

Cell Construction


An infected Caterpillar


A grown Caterpillar





A pupa. A Giant Red-eye pupates inside a cell that it makes out of the palm / banana leaf. The one shown below fell out of the cell and died later. Do not attempt to open the cell as it may expose them to predators.


This is how the a cell looks like when a pupa is inside.

The observations are made during Nov / Dec - 2016 from South India.

 The spots near the white line starts to grow bigger and hair like bristles are seen


 Some of the spots near the edge turn bluish in the final stages


The final stage caterpillar builds a string and prepares for the metamorphosis
