Thanks Wolfie. Time to see how Z handles a blue bottle. He probably could have handled a BB an instar ago, but I would rather feed a bunch of smaller house flies then stress out my lil buddy with something too big. I'm an over protective parent I guess, lol.
I did email the breeder about what flies came with the mantis and what I should be feeding. Her reply was..."It would have been either D. hydei or houseflies. The O. gracilis is pretty strong for their size, so will take either at L2." I know Tito molted once since I had him, so house flies it is. (I only have house and BB)
