I'm not sure whether I should be feeding my ants sugars while they hibernate. I've got Lasius flavus, niger and umbratus and Myrmica rubra. They've been in the fridge in test tubes at 8C since the end of October. Should I give them sugars while they're hibernating? I'm pulling the Myrmica rubra out at the start of February as I've read they're fine with 3 months, but will leave the Lasius in until the end of March.
Should I be putting sugar water in their test tubes to get them through hibernation? I'm especially concerned about the Myrmica as their gasters are so much smaller than the Lasius.
Many thanks for any advice.
