I have seen cannibalism in idolomantis even on first instar, which happen during the ill-fated shipment where the idolo ooth hatched during shipment for me, so no doubt they will eat each other rather than starving themself to death. But with plenty of food, they are dong alright together, not sure if "the larger they get, the less cannibalism they are" is true, mine been doing alright without any issue keeping together now at 6th/7th instar.Yeah i saw that thread.I think the older they get the less likely they are to feed on each other, mine are all 5/6th instar now, would it be ok to keep them together, cos it's a pain in the backside removing tupperware lids to add flies into the containers. Flies are so damny annoying to handle too, so would rather smack in a pot of them than hand pick (tweezer) each fly individually.
And even after refridgerating, they warm up too quickly!
How long should you leave them in the fridge for?!
Few crappy pics here
It could have been worst.... i lost about 20 hatchling in that shipment, although 75% of the total hatchling miraclely survived.Ouch! A sad scene...
