[Nhcoll-l] Mold in butterfly antennae - possible contamination ofthe collection

[Simon Moore]

Hi Dirk,

I don't think that it matters - either concentration does the job and application of the spirit does not seem to embrittle the antennae further.

It should work well on fish skeletons too (providing that it doesn't create solvency problems with any adhesives, as you say) plus I have also used it on taxidermy with great success as well.

With all good wishes, Simon

  Hi Simon!

  Which concentration: 75% or 96%?
  (dehydration should not be an issue in dried insects, I guess :-) 

  Would this work also for mounted fish skeletons (unless it does not corrode the glue)

  Best wishes
  Dirk

    I have always found the best way is to apply (very gently, using a fine artist's brush) a small amount of IMS.  This has always worked well for me and the mould has never returned.

      Dear all,



      I have recently started curating the insect collection here in the Museum and I am starting to learn how to prepare the insects.

      I have received a butterfly which I prepared but then I realized it had some mold already growing in the antennae and eyes, though not much. 

      I have meanwhile dried it at 55ºC for about 30 minutes and then for 3 days at room temperature.



      What I wanted to know is how to carry on regarding this issue? Is there a way to clean it, or kill the mold? I imagine that freezing won't cut for the mold.

      If I put it in a collection box will this potentially contaminate other specimens? (I have been keeping the collection room at around 50% humidity)



      In this case, it is not a rare specimen so if is a liability I can just discard it. But what if was something important?



      Thanks for your help!



      Best regards.
