I am interested in evaluating the potential dispersal of mayflies nymphs in streams to quantify dispersal as a structuring mechanism of metacommunities. I have tried some available dyes (such as rose bengal), but they are not being efficient.

which is your major problem, washing? durabilitty? You can use an extrac from ginger that is an strong pigment with no toxicity, but you should try first to confirm is not the same a human than a nymph.

Thanks for you coments. Both. But the most important is no toxicity.

Did rose bengal kill the mayflies? Or was it simply not taken up by them?
