Hi together,

sorry for necroing this thread.

Some Dipterists working with e.g. sciarids recommend the use of 1% formaldehyd-solution, because it saves structures by immediatly hardening the objects. This seems to be a contradiction.

At present I use this fluid in Malaise trap and everything looks quite good. The only disadvantage seems to be that everything gets very stiff.

What do you think about this?

Regards
Ralph
