Fruit flies are perfect, for young mantids, but they will only take these up to 3rd instar maybe 4th for ghosts. House flies, moths, bees are a great food source as they are covered in polen which is great for mantids(do be careful though as they sometimes have a nasty bite, just make sure they go to adults and sub adults of large species). What most on here do is they get maggots from fishing shops, keep them in the fridge and take a few out every now and then to hatch them into flies(never a favourite of my mum:lol
. I got a pint of maggots for £2.20 last week which will last me a very long time(make sure you do this in advance as sometimes they take longer to hatch than expected). Anything that flys your mantids will love- so will your beardie :lol: .Gongys are a really nice species but I would do quite a bit of reading on them, although some find them hard to care for but I disagree they seem to be pretty hardy but just make sure you keep them hot, dry and feed them flies and they will be happy. I think it may be because I keep reptiles I am used to having all the heat bulbs and extra work.
