These are mesostig mites on my Gromphadorrhina portentosa! :)
In terrariums they are found on other roaches as well, but in the nature they are restricted only to hissers.
Hello!
I am acarologist - that's mean, I am working with mites. :)
Main group of my interest is Mesostigmata mites.
BUT - I very like cockroaches, and have several species as pets.
I have found and identified some mite species related to cocroaches. Probably some of you also have found...
