Opposite of teneral?

Robin -

I think one needs to be careful to describe the feature or its state in
terms of its appearance, rather than imply a physiological condition.
Structures can become pigmented without becoming sclerotised. In the case of
the lampyrid pupa, I think "creamy-white, except ocelli which are brown" is
clear and accurate.

As for the opposite of teneral, I would use the term "mature", though in
most cases this might not be stated. There is an implication that an adult
insect that is not described as teneral would be mature.

Ken refers to the difficulty of "drawing the line" - this is an important
issue in many groups of insects, where post-teneral/mature individuals
continue to change their appearance. Older female dragonflies may take on
the blue pubescence normally associated with males, while in several groups
of Diptera, older individuals change colour - green blowflies become bronze
or copper coloured, and the pubescence of shoreflies often changes from
silver to gold. Occasionally these age-related colour-morphs have been
described as new species.

Hi Taxacomer,

Does anyone know a single-word term for the opposite
When an organism, or part of it, becomes darker after
having been creamy white, does that mean that the organism,
or part of it, is now slerotized?
Please see below.

I am reviewing a manuscript, and the authors have written:

"Simple eyes eventually become brown."

It is a lampyrid pupa under discussion, and shown are two
views of the pupa.  The pupa remains creamy white, but
acc. to the authors, the ocelli turn brown.

Perhaps more discussion is needed.  For example,
"Ocelli brown, pupa creamy white."

Perhaps it should read, "Ocelli pigmented, pupa
creamy white."

Any help or suggestions from anyone?
