that could be a effect of lack of fat.Could temperature affect beta carotene conversion?

I also wonder if the amount of the fat we feed is not enough to allow conversion. Anyone?
Sorry to dig this thread back up but thought i would throw a fresh theory that they may obtain some vit A from the large diversity of butterflies, moths & caterpillars in the trees & shrubs, extractThat's what I'm wondering. Back to my searching I guess.

Sourced from link you shared :
Retinol and β-carotene were detected in some butterfly caterpillars, such as the species Imbrasia oyemensis, Nudaurelia oyemensis, Ichthyodes truncata and Imbrasia epimethea containing 32–48 μg of retinol and 6.8–8.2 μg of β-carotene per 100 g of dry matter. The level of retinol per 100 g of dry matter was less than 20 μg and the level of β-carotene was less than 100 μg in the case of yellow mealworms T. molitor, superworms Z. morio and house crickets A. domesticus [22], [36], [38]. According to Finke [36] several species of lepidopteran larvae and the soldiers of one species of termites (Nasutitermes corniger) contain significant quantities of preformed vitamin A (retinol), but in general, insects do not appear to contain much preformed vitamin A.
Don't you mean convert carotenoids into retinol?Something else i recently seen an article on an enzyme found in swallowtail butterfly that can convert retinol into beta- carotenoids thought it might be further food for thought.
Crossed my mind as Its almost like chameleon exist to eat winged things it really excites them which im sure you can agree. Is there enough retinol explain the prEvit & the beta_k in F.pardalis eggs im wondering
Nope on the contrary, really interesting though. Although i was more trying to find out why a migration of butterflies disappear heading towards Madagascar. Stumbled on this study of Japanese swallowtails.Don't you mean convert carotenoids into retinol?
Off topic, no one knows where they end up i say in a chameleons gut, unfortunately they dont reach MadagascarI'd love to read that. I wonder why there would be a need to do that?
Sorry I have gotten confused and not able to grasp this pre and pro. Are we talking beta carrotein or vitamin a when speaking of pre and pro?So I guess we'd need to examine wild chameleons to see if they have sufficient/different amounts of prEformed vitamin to see if that was the difference?
