I'm breeding crickets so I can have tiny crickets for my tiny pacific chorus frog. The bigger ones are fed to my pacman. My crickets breed just fine in the summer, but they refuse to breed in the winter even with heat and lights. All my breeders suddenly died but when I went to clear the tank, there were these tiny ant-like bugs crawling around. I picked up the cricket's food dish and got a closer look at them. They turned out to be fruit flies, but they had absolutely no wings! My pacific loves these things. I can't find any live cultures anywhere around here, so I thought I'd have to breed only crickets and feed the tiny ones to my tiny frog. I was wondering if this has happened to anyone else? and how can I keep them this way? Were they attracted to the dead crickets or the crickets food?
