Trogonoptera brookiana forms?

[jasm]

Hello all!

I was scrolling through the good ol' eBay the other day when I came upon these Trogonoptera brookiana specimens. The seller has a few different listings and most say form "hecata" but there's another one is labeled form "caeruleus". Never seen (or heard) of either of them before and, after reading through some different discussions held here on the form about blue Ornithoptera, was wondering if this could be the result of a UV bath or something of the sorts. Link & picture below...

This is T.trojana and I’m pretty sure it’s been UV treated.
All of his specimens look kind of greasy

My bad Paul. You correct. The form "caeruleus" is for the T. trojana male and the form "hecata" is used for the T. brookiana male.

Does UV treatment normally make wing surfaces look 'kind of greasy'? I can see what you mean in the photo above.

Personally I cannot condone UV treatment for financial gain. Chemical or temperature treatment of pupae to induce aberrations is acceptable, but artificially changing the colour of an already dead butterfly is NOT.
