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

[Dirk Neumann]

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
