That's interested that two of your Namea molted so close together. I think I remember @Dave1969 also mentioning all of his molting at the same time recently as well. Do they have seasonal molts, do you know?
@Arthroverts I do try, I have an ad on Gumtree letting people know I'm after certain males, but I can only convince so many people to help me out.
With the assistance of a very helpful private property owner last year, I got some pretty interesting data that shows various species occupying the same areas seem to take turns maturing and wandering. Like, every week or 2 there was an influx of a different species of male (Nemesiidae matured first, then it was Atracids, then Idiopids, then Actinopodidae and finishing with Diplurids very late into the following year). Nemesiidae appear for a notably longer time period than the other groups and the males also live the longest, comparable to some T's.
