@HS. The crickets im getting does look in bad shape at the moment. I use crickets from crickets from africa. Usually if I feed them some apple they will stay alive for a month, but these days they dont even make a week. And when they die they turn all black.
Ive got a lobster roach colony, but its still small and dont want to destroy it before I gets going.
@ Gemini: Yes its the variables that makes it difficult. One tries one's best to keep everything constant, but unless you have a temperature and humidity controlled T room like RobC its basically impossible. And even he gets unexplained deaths. Its just part of life and the hobby that we cant change.
And just for interest sake. Masta splinta you were correct bud.

It was a female. Checked last nite through the scope.
