I've seen a couple of threads refering to 'Black crickets'. Is this a reference to Gryllus crickets like the North American field cricket, or is it something else? I have North American field crickets everywhere around my area this time of year. They seem to get alot 'meatier' than Acheta. I'm considering trying culture them, but I'm not sure if they will breed year round in captivity, as they have a pause in reproduction in the winter.
