I have an adult praying mantis, unsure of gender, although I suspect it is a male. Molting always went well and it had been eating quite voraciously. One day I tried crickets which it gobbled up and LOVED. Then I purchased some feeder blue bottles and houseflies. The mantis kind of turned up it's nose at those, so I figured, try crickets again. It munched on a cricket and mangled it, then let it go. The cricket is still alive. It also started eating a blue bottle, tore off it's wing, and let it go, too. And now it's not eating and hunting like it used to. There are also some fruit flies in there, but it is an adult now, and think the fruit flies might be too small, although it does seem to eat them. It just doesn't seem to have much of an appetite now. What could be going on with it? This started a few days ago.
