The first question is, what do you mean under "abnormal wings"?

Many factors affect this, not only food. Emerging from pupa is the process which usually affects the shape / form of butterfly wigs.

I agree with Dmitry Telnov.  The difficulty for a regular expansion of the wings in an emerging butterfly can depend, for instance, on an inadequate relative humidity or/and temperature of the environment in this very delicate phase of insect metamorphosis. But "abnormal wings" can also be due to other factors,

Dear Sir,

The abnormal wings I mean, butterfly wings is crippling and can't develop like a normally wings, although they fed on natural food contain more nutrient than artificial diet. Yes you right ~ when they emerging from pupae, I saw the stand for butterfly hanging affect to successful process.  Commonly they need something hard to support emerging from pupae. Thank you very much your answer. 

To Rinaldo Nicoli Aldini

Dear Sir,

Thank you very much your answer to my question. When I'm doing my last observation, it's a long dry season and their larvae fed only in Aristolochia stem before pupating. Dry season makes more of natural food was drying. I think humidity and environment temperature affect their development process to be butterfly. Please look at my picture, they can survive only 3-5 hours. It's so sad look at them. Thanks again for your attention.

In addition to befitting relative humidity and temperature (but also the atmospheric pressure can be an important factor affecting the eclosion), for an optimal expansion of the wings it is often necessary (as you yourself mention) - and not only in butterflies and moths but also in many other insects with large wings (dragonflies,  locusts, lacewings, and so on) - that the adult insect during and immediately after emergence (for approximately one or more hours) can have at disposal an oblique or vertical hard support (e.g. a branch with minor lateral branches, or a 'ceiling') for hanging down. In this way the insect can assume the suited posture for an optimal wing expansion (due to both diffusion and pressure of haemolymph into the wing veins, and to the force of gravity) up to the cuticle sclerification of wing membrane and veins (which form the 'framework' of the wing); then the definitive shape is reached. The relative humidity in my opinion is a very important factor affecting, during adult emergence as well as during pupation and all the pupal stage, the result of a normal shape of the insect. To avoid a r.h. too low during these phases, if you don't have a climatic chamber, you can try to use periodically a water sprayer in the box containing the pupae. Some people who rear butterflies use this empiric way, also useful or necessary (depending on the environment and food conditions) during larval rearing.

Dear Sir,

Thank you very much your explain, it add a new knowledge for me especially larvae butterflies process to be an adult. On my first observation, I’m confuse ~ I think butterfly wings development only affect by their nutrition on larvae stages. After our simple discuss here, I’m understand more about it. Thank you for your attention. I’m very appreciate it.

Sincerely yours,

Sri

I agree with Dr. Rinaldo Aldini. It is very important to have a hard support for the emerging pupae.

Dear Sir,

It's very interesting working with butterfly and study all of the things including their development process.  Thank you very much your answer.

It should be added that the complete stretching (expansion) of the wings in an emerging or just emerged butterfly (or other insect) can be also favoured by the filling of air into the tracheal ramifications which run inside wing veins,

Thank you very much your answer.

More than natural food, natural conditions are needed (i.e. humidity, temperature, pressure) -in your case, most natural possible-; to minimize stress by external factors. On the other hand, you should consider stress space, you may be pressing immature.

Dear Sir,

I agree with you about space of butterfly in emerging process. Actually Troides helena in endangered species status because wild hunting and other environment factor. More research for Troides spp pressure to bioecology and butterfly mating behavior. No one information about wing development of them. When first time I saw this phenomenon, I'm confuse about it. I was very fortunate here and got so many information about it. Thank you very much for your answer.

sincerely yours,

Sri

Hi Sri:

In addition to the lack of moisture and room to spread their wings mentioned by the other persons, there is another factor that can cause malformation of the wings in butterflies and other insects and is the sibling mating. To avoid this you need to get new parents to start a new breeding colony of Troides helena.

Hi Luis...

So difficult get Troides helena pupae in their habitat because they were endangered species status. Thank you very much your advice to me about sibling mating and new parents of butterfly. Based on limiting time and butterfly stock, commonly we was used new parents from laboratory. Thank you again.

regards,

Sri

Thanks to better explain his research. I agree with the previous answer, recessive alleles may be causing wing ´s malformation and perhaps this is the main factor causing the problem. You must try the crossbreeding of positive characteristics, should not have parental wild.

To : Felipe

Hello...

I'm very appreciate your detail information caused malformation of butterfly wings. Yup...my research was done in dry season, I think humidity, temperature and another factor in their habitat impact to larvae development. Off course, your question  very helpful for my butterfly future research.

best wishes,

Sri

Hi Sri,

You may like to look at a paper by Albert George Orr (its on researchgate) looking at inbreeding depression of Papilionids, including other Troidines (Ornithoptera richmondia and Cressida cressida). Bert found that Troidine swallowtails tended to show effects of inbreeding depression well before they produced adults (ie. high mortality in early instars), so while inbreeding depression is important in Troidines, it may not explain your eclosion issues.

Having experience breeding another birdwing (Ornithoptera euphorion) in captivity with licensed captive breeders while I was at university, I agree with the other comments that space and humidity are probably to blame. If you message me through reserarchgate, I will be happy to describe a setup that will help avoid crippled adults through low humidity.

I may also have some suggestions for your artificial diet and use of natural host material to help avoid crippled adults.

Hope this helps.

Regards,

John.

Dear Felipe,

Hello again...thanks for your suggestion to my research. I'm very appreciate it.

Dear John,

Hello....I hope a good day for you.  Thank you very much your answer to my question. I'm very appreciate and very helpful to my research.

best regards,
